FitFlop Size Guide: Comprehensive Information (Updated 02/27/2026)
Navigating FitFlop sizing requires careful consideration, as fit can vary between styles. This guide offers detailed charts, measuring tips, and regional conversions for a perfect fit, updated today!
Understanding FitFlop Sizing
FitFlop’s unique biomechanical engineering significantly impacts how their footwear fits, differing from traditional brands. Their integrated arch support and cushioned midsoles influence the overall feel and require a nuanced approach to sizing. Unlike standard shoe fitting, FitFlop’s design encourages a snug, secure fit – not overly loose.

Many customers initially order their usual size, but often find a half size up provides optimal comfort, particularly with sandals. This is due to the foot naturally expanding within the footbed. However, this isn’t a universal rule; style-specific variations exist.
FitFlop utilizes both UK and EU sizing, which can be confusing for US customers. Accurate foot measurement is crucial, and referencing the official FitFlop size charts (detailed in subsequent sections) is highly recommended. Consider the sock thickness you intend to wear, especially with closed-toe styles like loafers and boots. Finally, remember that individual foot shapes vary, and FitFlop offers width options to accommodate different foot volumes.
FitFlop Size Charts: Women’s
Below is a comprehensive guide to FitFlop women’s sizing, converting between US, UK, and EU measurements. Please note these are general guidelines, and variations can occur between styles; Always prioritize measuring your foot length for the most accurate fit.
| US Size | UK Size | EU Size | Foot Length (inches) |
|---|---|---|---|
| 5 | 3 | 35 | 9.06 ‒ 9.25 |
| 6 | 4 | 36 | 9.25 ― 9.45 |
| 7 | 5 | 37-38 | 9.45 ― 9.65 |
| 8 | 6 | 38-39 | 9.65 ― 9.84 |
| 9 | 7 | 40 | 9.84 ‒ 10.04 |
| 10 | 8 | 41 | 10.04 ― 10.24 |
| 11 | 9 | 42 | 10.24 ‒ 10.43 |
For half sizes, we recommend sizing up. If your measurement falls between sizes, consider the style – sandals may benefit from the larger size, while closed-toe shoes might fit better with the smaller size. Refer to style-specific notes when available.
FitFlop Size Charts: Men’s
Understanding FitFlop men’s sizing is crucial for optimal comfort and support; This chart provides conversions between US, UK, and EU sizes, alongside corresponding foot length measurements. Remember that individual styles may have slight variations, so accurate foot measurement remains key.

| US Size | UK Size | EU Size | Foot Length (inches) |
|---|---|---|---|
| 7 | 6 | 39 | 8.86 ‒ 9.06 |
| 8 | 7 | 40-41 | 9.06 ― 9.25 |
| 9 | 8 | 41-42 | 9.25 ‒ 9.45 |
| 10 | 9 | 43 | 9.45 ‒ 9.65 |
| 11 | 10 | 44 | 9.65 ‒ 9.84 |
| 12 | 11 | 45 | 9.84 ‒ 10.04 |
| 13 | 12 | 46 | 10.04 ― 10.24 |
When in doubt, or if you fall between sizes, we generally recommend opting for the larger size. Consider the specific FitFlop style; looser fits are preferable for sandals, while a snugger fit may be desired for more structured shoes. Always check style-specific guidance if available.
Measuring Your Feet for FitFlops
Accurate foot measurement is the cornerstone of finding your perfect FitFlop size. Begin by tracing your foot on a piece of paper while standing, ensuring your weight is evenly distributed. Measure the length from the heel to the tip of your longest toe in both feet – discrepancies are common!
Use a ruler or measuring tape, keeping it parallel to the foot tracing. Measure in inches or centimeters, and use the larger measurement if your feet differ in size. It’s best to measure at the end of the day, as feet tend to swell slightly. Wear the socks you intend to wear with your FitFlops during measurement.
Compare your measurement to the FitFlop size charts (see sections above); Remember that these charts are a guide; individual styles can vary. If your measurement falls between sizes, consider your foot width and the style of FitFlop you’re purchasing. A wider foot might benefit from sizing up. Repeat the measurement process to ensure accuracy before finalizing your order.

Width Options Available in FitFlop
FitFlop generally caters to a standard foot width, but understanding their fit is crucial for optimal comfort. While they don’t explicitly offer ‘wide’ or ‘narrow’ width options across all styles, certain designs inherently accommodate varying widths.
Styles with adjustable straps, like many of their sandals, provide flexibility for a customized fit. These allow you to adjust the straps to comfortably secure your foot, accommodating slightly wider feet. Conversely, more structured styles, such as loafers or boots, may run narrower.
Customers with wider feet often recommend sizing up in these more structured styles. Consider reading customer reviews for specific styles to gauge their width. Some newer collections are beginning to incorporate designs with a more generous fit. If you consistently struggle with width, exploring alternative brands with dedicated wide-width options might be beneficial. Always prioritize comfort and proper support.

FitFlop Styles and Their Fit
FitFlop’s diverse range of styles necessitates understanding how each fits differently. Their signature sandals, known for integrated arch support, generally run true to size, but some styles with pointed toes may require sizing up. The Lulu sandal, a popular choice, often fits snugly, so consider a half size larger if you’re between sizes.
Loafers and slip-ons can vary significantly. Some customers find these styles run slightly small, particularly in the toe box. Checking individual product reviews is highly recommended. Boots, especially those with a more structured design, may also benefit from sizing up, particularly if you plan to wear thicker socks.
The newer Supersoft range tends to offer a more relaxed fit, prioritizing all-day comfort. Always consult the specific size guide for the style you’re interested in, as FitFlop continually refines its designs. Remember, individual foot shapes vary, so prioritize comfort and consider reading recent customer feedback.
Comparing FitFlop Sizes to Other Brands
Translating your size from other brands to FitFlop can be tricky, as FitFlop’s sizing often differs. Generally, those accustomed to US sizing may find FitFlop’s sizing comparable, but a slight adjustment might be needed depending on the style. Individuals typically wearing a size 7 in brands like Clarks or Birkenstock often find a 7 or 7.5 in FitFlop suitable.

Compared to European brands, FitFlop tends to run a half size larger. If you usually wear a 38 in European sizing, a 7.5 or 8 in FitFlop might be the best fit. Those familiar with UK sizing should note that FitFlop’s UK sizes align closely, but again, style-specific variations exist.
It’s crucial to avoid relying solely on conversions. Foot shape and width play significant roles. Utilizing FitFlop’s official size chart and measuring your feet accurately are paramount. Customer reviews often provide valuable insights into how FitFlop sizes compare to specific brands, offering a more personalized guide.
FitFlop Sandals Sizing Considerations
FitFlop sandals, renowned for their comfort, require specific sizing attention. Unlike traditional sandals, FitFlop’s integrated footbed impacts fit. Many styles feature a contoured footbed, demanding a snug, but not tight, feel. A little room at the heel is acceptable, preventing slippage during walking.
Consider the sandal’s upper design. Styles with straps across the instep may require slightly larger sizing to avoid constriction. For toe-post sandals, ensure adequate space between your toes and the post to prevent rubbing. Wider feet may benefit from sizing up, particularly in narrower sandal designs.
Pay attention to the material. Leather sandals tend to stretch slightly with wear, while synthetic materials maintain their shape. If purchasing leather, consider ordering your usual size, anticipating some give. Always prioritize comfort and functionality when selecting your FitFlop sandal size, referencing the official size chart for accuracy.
FitFlop Loafers and Shoes Sizing
When selecting FitFlop loafers and shoes, a precise fit is crucial for experiencing their signature comfort. Unlike sandals, these styles offer less inherent give, demanding a more accurate size selection. It’s generally recommended to measure your feet later in the day, as they tend to swell slightly.
Consider sock thickness. If you plan to wear socks with your loafers or shoes, account for the added volume when choosing your size. A snug fit is desirable, but avoid excessive tightness, which can cause discomfort during prolonged wear. Pay close attention to the shoe’s width, as FitFlop offers limited width options.
Review style-specific notes. Some FitFlop loafers and shoes feature a pointed toe or a narrower last. In such cases, sizing up may be necessary to prevent pinching. Always consult the official FitFlop size chart and customer reviews for insights into specific styles’ fit characteristics, ensuring optimal comfort and support.
FitFlop Boots Sizing Guide
FitFlop boots require a particularly thoughtful approach to sizing, due to the enclosed nature of the footwear and potential for varying shaft heights and widths. As with all FitFlop styles, accurate foot measurement is paramount – ideally, measure both feet as discrepancies are common.
Account for sock thickness and intended use. If you anticipate wearing thicker socks with your boots, especially during colder months, select a size that accommodates this extra volume. Consider whether you’ll be using orthotics; if so, ensure sufficient space within the boot’s toe box.
Pay attention to boot shaft height and width. Taller boots may require consideration of calf circumference, while narrower boots may necessitate sizing up. Consult the specific product description for details on the boot’s construction and fit. Customer reviews often provide valuable insights into real-world sizing experiences, helping you make an informed decision for optimal comfort and style.
Dealing with Half Sizes in FitFlop

Navigating half sizes with FitFlop can be tricky, as the brand’s sizing isn’t always perfectly consistent across all styles. Generally, if you typically wear a half size in other brands, it’s advisable to size up to the nearest whole size in FitFlop, particularly for sandals and slip-ons.
However, for enclosed shoes like loafers or boots, the best approach depends on your foot shape and the specific style. If you have narrow feet, sticking with your usual half size might be preferable to avoid excessive room. Conversely, wider feet may benefit from sizing up.
Consider the material of the shoe. Leather and suede tend to stretch slightly with wear, so a snug fit initially might be acceptable. Synthetic materials offer less give, so prioritizing a comfortable fit from the outset is crucial. Reading customer reviews specific to the style you’re interested in can provide valuable insights into how it runs – true to size, small, or large.
FitFlop Size Variations by Region (US, UK, EU)
FitFlop utilizes different sizing scales depending on the region where the shoes are sold, creating potential confusion for international shoppers. Understanding these variations is crucial for ensuring a proper fit. US sizing is the standard for North and South America, while the UK scale is predominantly used in the United Kingdom and Commonwealth countries.
European (EU) sizing differs from both US and UK systems and requires careful conversion. A US women’s size 8, for example, typically translates to a UK size 6 and an EU size 39. Men’s sizes also exhibit similar discrepancies; a US men’s size 10 corresponds roughly to a UK size 9 and an EU size 44.
FitFlop provides conversion charts on their official website, but these should be used as a guide only. Individual styles may run slightly differently. Always measure your feet and compare them to the specific size chart for the region you are purchasing from. Utilizing a reliable online size conversion tool can also assist in navigating these regional differences, minimizing the risk of ordering the incorrect size.
Common FitFlop Sizing Issues & Solutions
Many customers report FitFlop sizing inconsistencies, often finding they require a half or even a full size larger than their usual shoe size. This is frequently due to the brand’s emphasis on comfort and the contoured footbed, which can take up additional space within the sandal or shoe.
A common issue is heel slippage, particularly with the slimmer styles. If this occurs, trying a smaller size or utilizing heel grips can provide a more secure fit. Conversely, if toes feel cramped, opting for a larger size is recommended. Another frequent problem is width; FitFlops generally run narrower, so those with wider feet may need to consider styles specifically designed for wider feet or size up.
To resolve sizing issues, carefully remeasure your feet and compare them to the FitFlop size chart. Utilize the return and exchange policy if the initial size is incorrect. Consider reading customer reviews for specific styles, as they often provide valuable insights into the true fit. Don’t hesitate to contact FitFlop’s customer service for personalized assistance.
FitFlop Return and Exchange Policy Regarding Sizing
FitFlop generally offers a flexible return and exchange policy, acknowledging the potential for sizing difficulties. Typically, unworn items with original tags can be returned for a full refund or exchanged for a different size or style within a specified timeframe – often 30 to 60 days from the purchase date.
However, specific conditions apply. Returns initiated after the timeframe may be subject to store credit or denial. Items showing signs of wear, beyond trying on indoors, are usually not eligible for return. Customers are often responsible for return shipping costs, unless the return is due to a FitFlop error, such as a defective product or incorrect shipment.
To initiate a return or exchange, customers usually need to visit the FitFlop website and follow the online instructions, obtaining a return authorization number. It’s crucial to retain proof of purchase. Always review the current policy details on the official FitFlop website, as policies can change. Understanding these guidelines ensures a smooth process if sizing adjustments are needed.
Customer Reviews on FitFlop Sizing
Customer feedback consistently highlights FitFlop sizing as potentially inconsistent. Many reviewers report needing to size up, particularly when purchasing sandals, citing a snug fit or the feeling that their usual size is too small. Others mention that certain styles, like loafers or boots, run true to size, creating confusion.
A recurring theme is the variability between different FitFlop models. What fits perfectly in one style might be too large or small in another. Wide-footed customers frequently recommend sizing up one or even two sizes, or seeking out styles specifically designed for wider feet. Several users suggest carefully measuring foot length and comparing it to the official FitFlop size chart.
Positive reviews often praise the comfort once the correct size is found, but emphasize the importance of reading multiple reviews before purchasing. Many customers recommend ordering multiple sizes if unsure, taking advantage of the return policy. Overall, customer experiences underscore the need for diligent research and potentially ordering multiple sizes to achieve the optimal fit.
FitFlop Size Guide for Specific Foot Conditions (Wide Feet, Bunions)
FitFlop caters to a range of foot needs, but specific conditions require careful consideration when selecting a size. Individuals with wide feet consistently benefit from sizing up, often by a full size or even two, depending on the style. Look for styles explicitly labeled as “wide fit” for optimal comfort, as these offer increased width in the forefoot area.
For those with bunions, styles with a softer, more flexible upper material are crucial to avoid pressure and irritation. Avoid pointed-toe designs and opt for sandals or shoes with a roomy toe box. The Lulu sandal is frequently recommended due to its adjustable straps and accommodating fit.
Customers with high arches may find the contoured footbed of many FitFlop styles supportive, but ensuring adequate length is still vital. Consider measuring foot length at the end of the day when feet are most swollen. Prioritize styles with adjustable features to customize the fit and minimize discomfort. Consulting customer reviews specifically mentioning similar foot conditions can provide valuable insights.
FitFlop Size Guide for Children
FitFlop offers a delightful range of sandals and shoes for children, but accurate sizing is paramount for growing feet. Children’s feet grow rapidly, so regular measurements are essential – ideally every two to three months. Always measure both feet, as sizes can differ. Use a ruler or FitFlop’s printable size guide to determine the correct length in centimeters or inches.
FitFlop children’s sizes generally correspond to UK sizing, with clear conversions available to US and EU sizes on their official website. When in doubt, it’s generally recommended to size up, allowing room for growth and preventing discomfort. Avoid purchasing sizes significantly larger, as this can affect gait and stability.
Consider the style of the shoe. Sandals with adjustable straps offer a more customizable fit, while closed-toe shoes require a precise length measurement. Check customer reviews for feedback on specific styles and sizing accuracy. Prioritize breathable materials and flexible soles to support healthy foot development. Remember to account for socks when measuring for closed-toe options.
Where to Find the Most Accurate FitFlop Size Information
For the most reliable FitFlop sizing guidance, the official FitFlop website is the primary resource; It features comprehensive size charts for women, men, and children, covering UK, US, and EU conversions. These charts are regularly updated to reflect any changes in their sizing standards, ensuring accuracy as of today’s date.
FitFlop also provides a printable size guide, allowing you to measure your feet at home and compare the measurements to their charts. This is particularly useful when ordering online. Additionally, their website often includes style-specific fitting notes, highlighting any variations in fit for particular designs.
Authorized FitFlop retailers, both online and in brick-and-mortar stores, should have trained staff who can assist with sizing. Checking customer reviews on the FitFlop website or other retail platforms can provide valuable insights into real-world fit experiences. Avoid relying solely on third-party size charts, as these may not be up-to-date or accurate. Always cross-reference with official FitFlop resources.

Tips for Ordering FitFlops Online
Ordering FitFlops online requires a proactive approach to ensure a perfect fit. Begin by meticulously measuring your feet – both length and width – using FitFlop’s printable guide, available on their official website. Compare these measurements carefully against their size charts, noting any discrepancies between UK, US, and EU sizes.
Read product descriptions thoroughly, paying attention to any specific fitting recommendations for the style you’re considering. Customer reviews are invaluable; search for comments regarding sizing accuracy – do they run large, small, or true to size? Consider ordering from retailers with generous return policies, allowing you to exchange sizes if needed.
If you’re between sizes, it’s generally advisable to size up, especially for sandals. Be mindful of width options if available, and choose accordingly. Keep your original packaging and tags intact until you’ve confirmed the fit. Finally, double-check the retailer’s shipping and return information before completing your purchase.
FitFlop Sizing and Arch Support
FitFlop’s signature technology centers around integrated arch support, influencing how their footwear should fit. A proper fit is crucial to experience the full benefits of this support; too loose, and the arch won’t be correctly positioned, diminishing the ergonomic effect. Too tight, and it can cause discomfort and pressure points.
When selecting your size, consider the intended use. Styles designed for walking or all-day wear require a snugger fit to maintain optimal arch support during movement. Sandals, while more relaxed, still need enough security to prevent slippage. Pay attention to the insole contour – your arch should align comfortably with the raised area.
If you have high arches, you might benefit from a slightly wider width to accommodate the support. Conversely, those with lower arches may prefer a standard width. Experiment with different styles, as the arch support level varies. Always prioritize comfort; a well-fitting FitFlop should feel supportive and cushioning, not constricting or painful.
