Once the foot is in the boot, fasten the buckles to the midpoint. If your kid can go further, this means that the boot size is not right for them. Once the boot is fastened, they must bend the leg 3 times by pressing hard on the shins, to roll the heel back into the boot. Standing upright, they should be able to brush the front of the shell. When you flex, your foot should move backwards so you can no longer feel the end.
