• Wide

A last width between 100 mm and 101 mm (MP 26./26.5), considered average, offers greater volume and a more relaxed fit ideal for most skiers. To identify one’s preferred last, the foot’s width between the first and the fifth metatarsal bone is measured to gather an overview of the skier’s natural foot shape and volume.
