Dialed with a progression-friendly medium-soft flex, the Rook brings you an optimum blend of mobility and support for riders honing their skills from groomers to first tracks through powdery bowls. The Rook's super-convenient Boa lacing system secures the boot's upper and lower zones with the quick spin of a dial, making tightening a breeze especially when you're re-adjusting mid-mountain. On the inside, you'll find a thermo-moldable liner that conforms to your foot's specific contours and internal J-bar supports that lock your heel to eliminate lift when you're mastering your heel-to-toeside carves. Toss in an impact-absorbing +Slime midsole as well as a lightweight Grip outsole for a well-rounded boot that's ready to take your riding to the next level.
