The Salomon X-Pro 130 is a powerful boot for aggressive experts who are looking for a fit that can quickly be dialed in. Salomon's 360 Degree Custom Shell can be heated and molded by an Authorized Salomon Dealer in a special oven. Once the shell is hot enough, the bootfitter will set your feet inside the boot. As it starts to cool the shell will mold to adapt to the shape of your foot. A 24mm Oversized Pivot adds a beefy connection between the upper cuff and lower shell for a high amount of energy transmission to your skis. The TwinFrame2 Construction has reinforcements on the sole and spine reduces torsional twisting of the shell when you are cranking out high speed turns. A 45mm World Cup Claw Power Strap keeps a tight wrap across your shin and adds even more rebound to this high performance boot. The My Custom Fit 3D Race Liner is also fully customizable by heat for a truly dialed in fit inside and out.
