The Shift Pro 90 AT sidles comfortably into that ski boot sweet spot, providing reliable power when shredding on the downhill while excelling as a comfortable and flexible backcountry tourer. With a cuff design precisely built for lady powder monsters, this boot is a true one quiver wonder.

Like it's brothers in the Shift Pro line, the 90 is built to shred at high speed, providing power transmission and edge-to-edge control. The thinner shell wall construction allows the foot to be closer to the shell and provides enhanced sensations, more power, and direct transmission. Toss in a seamless and moldable liner and you've got a bad-to-the-bones downhill rager.

When it's time to hit the skin track, do not go digging into the gear closet for your old touring boots. Nope. Flip the low-profile walk lever, customize the 4 mircro-adjustable buckles, tinker with your 35mm Power Strap, and this downhill monster is transformed into a reliable, comfortable, and responsive boot well beyond the resort gates.
