The Salomon STH Driver binding construction may be an oldie, but it’s consistently a goodie, thanks to its metal base plate and heel track that ensure stability and durability while reducing rip outs. STH’s burliest model is the 16, with a 9–16 DIN, and is a must- have for big mountain chargers. The Driver is the lightweight cous- in to the original STH Steel, which used a full-metal construction for ultimate power transfer performance, stability and durability. The Driver replaces a metal toe and heelpiece with composite materials making it lighter without sacrificing performance or safety.
