FitFlop Size Guide
About FitFlop: FitFlop is a renowned comfort footwear brand specialising in innovative shoe technology designed to promote natural body alignment, minimise muscle exertion, and optimise energy. Each pair of FitFlop shoes is meticulously engineered with attention to the position of your feet and toes, allowing plenty of room for unrestricted movement and all-day comfort. FitFlop shoes are ideal for anyone seeking maximum support and comfort, whether you're walking, running, or simply enjoying your everyday activities. The brand accommodates a diverse range of widths and foot shapes, ensuring that everyone can find their perfect fit.
How to Measure Your Feet
To ensure you select the correct FitFlop size, follow these simple measurement steps:
- Prepare: Remove your shoes and socks, and stand on a flat, hard surface. Have a ruler or measuring tape ready, along with a piece of paper and a pen.
- Measure your foot length: Place your heel against a wall, and mark where your longest toe reaches on the paper. Measure the distance from the wall to the mark in both centimetres and inches.
- Measure your foot width: Measure across the widest part of your foot (typically across the ball of the foot). Record this measurement in both centimetres and inches.
- Measure both feet: Repeat the process for your other foot, as feet often differ slightly in size. Always use the larger measurement when determining your size.
- Compare with the size chart: Locate your measurements in the appropriate size chart below to find your corresponding UK, EU, and US sizes.
- Consider width: FitFlop shoes are designed with generous room for natural movement. If you fall between two sizes, we recommend sizing up for optimal comfort and to accommodate any swelling throughout the day.
- Account for the time of day: Feet tend to swell slightly as the day progresses. It's best to measure your feet in the afternoon or evening for a more accurate representation of your everyday size.

Understanding FitFlop Sizing
FitFlop shoes are engineered with a particular focus on comfort and natural foot alignment. As a result, sizing across FitFlop styles may feel slightly roomier than footwear from other brands. This is intentional—the brand pays careful attention to the position of your feet and toes, ensuring that natural movement is never restricted.
The width of FitFlop shoes may vary depending on the style, silhouette, and the specific technology built into the sole. For example, shoes utilising the same core technology will typically have a similar width fitting. If you're uncertain between two sizes or find that you're between size ranges, we strongly recommend sizing up to ensure maximum comfort, particularly if you plan to wear the shoes for extended periods.
Important Note: All sizes provided are approximate. Individual fit may vary depending on the specific style, your foot shape, and personal preference regarding tightness or looseness.
FitFlop Product Categories & Fit Information
Sandals & Flip-Flops
FitFlop sandals, including toe-post sandals and casual flip-flops, are designed for warm-weather comfort. These styles typically fit true to size. If you have particularly wide feet or prefer a roomier fit, consider sizing up. The toe-post design of classic FitFlop sandals provides arch support and helps distribute pressure evenly across your foot.
Trainers & Casual Shoes
FitFlop trainers and casual shoes are engineered for all-day wear and come in both lace-up and slip-on styles. These shoes are designed with a slightly spacious fit to accommodate natural foot swell. If you fall between sizes, we recommend sizing up, particularly if you intend to wear these shoes for extended periods or with thicker socks.
Boots & Closed-Toe Styles
FitFlop boots maintain the brand's commitment to comfort and support. Closed-toe styles should be fitted to allow approximately half a thumb's width of space between your longest toe and the inside of the shoe. Sizing up by half a size may be beneficial if you plan to wear thick socks or thermal layers.
Platforms & Statement Shoes
Platform shoes and statement pieces from FitFlop generally fit true to size, though the added platform height may affect how the shoe feels on your foot. Ensure that your heel is secured comfortably within the shoe and that there's no slipping when you walk.
Sizing Tips
- Always size up if between sizes: FitFlop shoes are designed for all-day comfort with generous room for natural foot movement. If you're uncertain between two sizes, choose the larger size to ensure optimal comfort and to avoid unnecessary tightness.
- Measure both feet: Most people have feet of slightly different sizes. Always measure both feet and use the larger measurement when determining your size to ensure a comfortable fit for both shoes.
- Measure in the afternoon: Feet naturally swell throughout the day due to increased blood flow and activity. Measure your feet in the afternoon or evening for a more accurate representation of your typical shoe size.
- Consider the style and sole technology: Different FitFlop styles and sole technologies may have varying widths and fits. Shoes using the same core technology will typically have a similar width, so if one style fits well, similar models should as well.
- Account for socks and insoles: If you plan to wear thick socks, thermal liners, or custom orthopaedic insoles with your FitFlop shoes, consider sizing up to accommodate these additions comfortably.
- Check return policies before ordering online: When purchasing FitFlop shoes online, review the retailer's return and exchange policy. This allows you to order multiple sizes and keep the best fit, reducing the risk of ordering an incorrect size.
- Visit a physical store for professional fitting: If possible, visit a FitFlop stockist or specialist shoe retailer to have your feet professionally measured and to try on shoes in person. Staff can provide personalised recommendations based on your foot shape and intended use.
- Break in period: Whilst FitFlop shoes are designed for immediate comfort, allow a short break-in period of a few days to a week. The shoes will mould to your foot shape and become even more comfortable with wear.
International Size Conversions
FitFlop provides sizing in UK, US, and EU formats to accommodate customers worldwide. The tables above offer comprehensive conversions. Remember that sizing standards can vary slightly between countries and manufacturers, so if you're ordering from a country where you don't typically purchase shoes, it's worth double-checking your measurements against the size chart.
