The X-Pro 80 from Salomon is a great boot for the solid intermediate skier that has a medium to narrow forefoot and medium leg shape. The X-Pro 80 is made with a Twinframe Construction that uses a more rigid plastic on the sole of the boot and surrounding areas that add extra responsiveness and control when skiing at high speeds. A 35mm Velcro Strap acts as a fifth buckle on the boot to keep a firm wrap across your shin and increase your leverage on the boot. Salomon's 24mm Oversized Pivot directs energy and power directly to the edges of your skis by having a wider, stronger connection between the upper cuff and lower shell. The X-Pro 80 has the My Custom Fit 3D Sport Liner that has 5 different layers of foam and Thermoformable Material in the tongue and ankle pockets that can be heated to jump start the breaking in process and eliminate minor pressure points. The 80 flex rating is supportive for the intermediate skier that will want to grow and develop their skills with confidence and control, without being too demanding or causing fatigue. If you are looking for a boot that has a medium to narrow fit in the forefoot and leg that will be strong enough for tacking the blue squares with ease, the X-Pro 80 from Salomon will make a good fit for you.
