The Rossignol Track 80 is a great option for beginner to advanced intermediate skiers with a wide forefoot and medium calf volume. Rossignol's Sensor Matrix uses a grid positioning on the upper cuff and lower shell that gives your foot a precise wrap while lowering the total weight of the boot without any compromise to energy transfer towards your skis. The Posi-Block Ski/Hike Mechanism makes for an easy strut on your way to the chairlift in the morning or the apres party in the afternoon. An Easy Entry Insert uses a softer plastic across the instep that allows your foot to slide into the shell effortlessly.
