Dont be tricked into thinking this is the standard STH 12. The use of the Driver toe piece, & its extra elasticity, makes it absolutely ideal for freestyle & general freeskiing. The Driver toe piece also improves boot contact with micro adjustment both laterally & vertically. Metal housings & 5 screws instead of the traditional 4 on the heel massively increase durability. DIN 4-12 (100mm brake).
