The Rossignol AllTrack 110 makes an excellent choice for the strong intermediate to expert skier looking for a medium width fit in both the forefoot and shaft of the leg. Rossignol's Posi-Block Ski/Hike Mechanism creates a wide range of motion when you pull up the lever located on the spine of the boot for hiking and walking with ease. Thinsulate Insulation adds extra warmth to the liner to keep you comfortable on days when the snow is good, but the temps are low. The Full Custom T3 Liner has dual density padding that can be heat molded or will start to adapt to the shape of your foot after only a few days on the slopes. Rossi's Generative Design Grid Technology has a grid structure on the exterior shell that improves the foot wrapping, reduces the total weight and enhances precision when you are really cranking turns.
