Size Guide

How to measure your foot

FlowFlip Co's flipflops are unisex. They come in double sizes, for example EU 42/43. For the best fit, use sole length as your main reference. Measure your foot, compare it with the sole length in the chart below, and then use the EU, UK, and US sizes as a guide.

To find the right size, measure your foot first. Use a sheet of paper, a pen or pencil, and a ruler. Measure on a hard floor, with your heel against a wall. Repeat for both feet and use the longer measurement.

How to use the size charts

Compare your foot length with the sole length shown for each size. Foot length and sole length are not the same measurement. The sole should be slightly longer than the foot. Sole length is the main reference. EU, UK, and US sizes are provided as a guide. Adult and youth charts follow FlowFlip’s product categories, which are based on BJJ rank systems rather than foot size alone.
