We typically suggest going for a slightly larger size than your usual size as the insoles can always be trimmed for the perfect fit.

To obtain your foot size, you can either rely on the shoe size that you generally wear OR measure the length of your foot.

All of our insoles are made from flexible materials, making them comfortable for any shoe!
