Don’t hesitate to consult the detailed charts and measurement instructions provided to ensure a comfortable experience.

Why FitFlop Sizing Matters

FitFlop’s core philosophy centers around biomechanical engineering, designed to enhance posture and comfort. However, the full benefits of this technology are only realized with a precise fit. Incorrect sizing can compromise the intended support and pressure distribution, potentially leading to discomfort or negating the ergonomic advantages.

A too-small FitFlop restricts natural foot movement, while a too-large size allows excessive slippage, reducing stability. Proper sizing ensures the midsole technology effectively absorbs impact and supports the arch. Considering FitFlop’s unique construction, relying on your usual shoe size isn’t always accurate. Therefore, carefully following the provided measurement guides and size charts is essential for maximizing comfort and experiencing the full potential of FitFlop’s innovative footwear.

Invest in the right size for a truly comfortable and supportive experience!

Understanding FitFlop’s Biomechanical Technology

FitFlop distinguishes itself through its integrated biomechanical technology, engineered to reduce impact and increase muscle activity with every step. This isn’t merely about cushioning; it’s about reshaping how your foot interacts with the ground, promoting better posture and potentially alleviating pressure points.

The secret lies in the carefully designed midsoles, which incorporate multiple densities to absorb shock and distribute weight more evenly. This technology aims to mimic natural walking patterns, encouraging engagement of key leg and core muscles. However, the effectiveness of this technology is directly linked to proper fit. A correctly sized FitFlop allows the midsole to function as intended, maximizing its benefits.

Understanding this technology underscores the importance of accurate sizing – it’s not just about comfort, but about optimizing the shoe’s biomechanical performance.

How to Measure Your FitFlop Size

Accurate foot measurement is crucial for selecting the perfect FitFlop size. Follow our step-by-step guide to determine your foot length and width precisely.

Step-by-Step Foot Measurement Guide

Measuring your feet accurately is the first step to finding your perfect FitFlop fit. Here’s a comprehensive guide to ensure you get it right:

1. Preparation: Place a piece of paper larger than your foot on a hard, flat surface.
2. Foot Placement: Stand with your heel against a wall and place your foot firmly on the paper. Ensure your weight is evenly distributed.
3. Tracing: Carefully trace around your entire foot, keeping the pen vertical.
4. Measurement – Length: Measure the longest distance from the back of your heel to the tip of your longest toe in millimeters (mm) or centimeters (cm).
5. Measurement – Width: Measure the widest part of your foot.
6. Repeat: Repeat these steps for your other foot, as feet can differ slightly in size.
7. Compare: Use the larger measurement from either foot to determine your FitFlop size using our size charts.

Important Note: Measure your feet at the end of the day, as they tend to swell slightly. Wear the type of socks you intend to wear with your FitFlops during measurement.

Measuring Foot Length

Accurately determining your foot length is crucial for selecting the correct FitFlop size. Begin by placing a piece of paper on a flat surface against a wall. Stand with your heel firmly touching the wall and your foot flat on the paper.

Using a pen or pencil, carefully trace the outline of your entire foot, ensuring the pen remains perpendicular to the paper. Once traced, measure the distance from the very back of your heel – where it touches the wall – to the tip of your longest toe. This measurement, taken in millimeters (mm) or centimeters (cm), represents your foot length.

Pro Tip: If your longest toe isn’t the big toe, be sure to measure to the end of that toe instead. Repeat this process for your other foot and use the larger measurement for accurate sizing.

Measuring Foot Width

Determining your foot width, alongside length, contributes to a perfectly fitted FitFlop. After tracing your foot (as described in the foot length guide), identify the widest part of your foot – typically across the ball of your foot.

Using a ruler, measure the distance between the two furthest points on either side of your foot at this widest point. This measurement, also in millimeters (mm) or centimeters (cm), represents your foot width. It’s important to measure while standing, as your foot expands slightly when bearing weight.

Consider this: FitFlop styles vary, and some may run narrower or wider. Knowing your foot width helps you choose styles that accommodate your foot shape for optimal comfort and support. Refer to the detailed size charts for width guidance.

FitFlop Sizing Tips & Considerations

When in doubt, size up, especially for in-between sizes. Different FitFlop styles – sandals, boots, or sneakers – may require adjusted sizing for a perfect fit.

Sizing Up for In-Between Sizes

Navigating in-between sizes with FitFlop can be tricky, but a simple rule generally applies: when unsure, it’s always best to size up. This recommendation stems from ensuring optimal comfort and preventing potential issues like squeezing or discomfort during wear.

FitFlop’s biomechanically engineered designs are crafted to provide support and cushioning, and a slightly larger size allows your foot to fully utilize these benefits without restriction. A too-small shoe can negate the ergonomic advantages, leading to rubbing, blisters, and overall discomfort.

Consider that feet can swell slightly throughout the day, especially during warmer weather or with increased activity. Sizing up accommodates this natural fluctuation, ensuring a comfortable fit even when your feet are at their largest. Furthermore, if you’re choosing between sizes and prefer a more relaxed fit, opting for the larger size is a sensible choice. Remember to always prioritize comfort and functionality when selecting your FitFlop size.

Considerations for Different FitFlop Styles (Sandals, Boots, Sneakers)

FitFlop’s diverse range of styles—sandals, boots, and sneakers—require slightly different sizing considerations for the perfect fit. While the core size charts remain consistent, the construction and intended use of each style influence how they feel on your feet.

Sandals, particularly those with slimmer straps, may benefit from sizing up if you’re between sizes, ensuring a secure yet comfortable hold. Boots, especially those with thicker linings or pointed toes, might require a half size up to accommodate socks and prevent constriction.

Sneakers, designed for more active wear, should fit snugly but not tightly. Allow for a thumb’s width of space between your longest toe and the end of the shoe. Always consider sock thickness when trying on boots and sneakers. Ultimately, prioritizing comfort and ensuring adequate space for natural foot movement is crucial, regardless of the FitFlop style you choose.
