The inner sidewalls of the boot shell and the liner are pre-formed in five different points to match the anatomical contours of the foot. In the shell, a little extra space has been moulded at four critical fit points: on the inner and outer sides of the forefoot as well as on the instep and the outer ankle.
Untouched flex, repeatable customization possible
