Frequently asked questions
How do I measure my foot?
Stand on paper against a wall, mark the longest toe, and measure heel to mark in centimetres. Measure in the evening when feet are largest.
Why do brands differ?
There's no enforced standard — lasts vary by brand and even by model, so foot length in centimetres is the most reliable guide.
