Designed for the all-terrain charger who never knows when they'll need to charge UP the hill as well as down, the Salomon Shift Pro 130 AT Alpine Touring Ski Boots rock a legit 130 flex along with a super functional walk mode that is as stealthy as a walk mode can be (the lever is minimalist and at the top of the cuff rather than along the rear spine of the boot). With perhaps the most popular 100mm fit in the business (taken from the S/Pro) and full Custom Shell HD heat molding capability, the Shift Pro 130 does do it all.
