Friendly Shoes Size Guide
To find the right size shoe, you first need to know your foot length. Follow our simple step-by-step instructions, and then match it with the size guides for men, women and kids below:
- Foot trace: Place a piece of paper on the floor, and put your foot (including AFO if you wear one) on it. Use a pen or pencil to trace the outline, and keep the pen as straight as possible for the most accurate drawing.
- Measure: Get a ruler or tape measure and find the full length of the outline in cm (from the back of the heel to the end of the longest toe). The longest toe may not be the big toe!
- If the feet are different lengths, measure the longest foot. Our insoles are removable, so you could always remove the insole from the shoe for the longer foot and double up in the shorter if needed.
- Try to measure feet in the afternoon. Our feet can swell in the day, and will be at their largest size, so you can get the most accurate measurement.
We’re here to help if you’re still not sure what size to go for. Just email us at hello@friendlyshoes.co.uk.
