The Rossignol Track 70 W is designed for the true beginner to solid intermediate skier who has a wide forefoot and medium to wide shaft of the leg. An Easy Entry Insert makes sliding your feet in and out of the boot very comfortable. The Posi Block Ski / Hike Mechanism means effortless walking when you flip the lever that sits on the rear spine of the boot. Rossignol's Sensor Matrix Construction uses a grid structure that wraps your foot with a strong energy transmission to your skis while reducing the total weight of the boot. The new Custom Comfort Fit T4 Liner has padding in all of the right places while keeping your foot supported and comfortable.
