Size guide

Every Avara size is built to a measured inner length (the insole, in millimetres). Match your child's foot length to the recommended foot length, and if the fit isn't right we'll help you exchange.

Which size?

Enter the length of your child's foot (heel to toe, in millimetres) and we'll point to the size with the right inner length.
