The Salomon X-Max 100 is a great ski boot for the strong intermediate to expert skier who has a narrow to medium width forefoot. The Twinframe Construction uses a stiffer and stronger plastic on the sole of the boot that enhances responsiveness and control when you are ripping down the mountain at fast speeds. Salomon's 360 Degree Custom Shell Technology is an easy fit solution that provides a comfortable and performance oriented fit, in little time. An Authorized Salomon Dealer can heat the shell in a special oven, then the hot shell is placed on your foot. As the shell cools it can adapt to the shape of your foot. A 24mm Oversized Pivot connects the upper cuff to the lower shell, and drives your energy right to the edges of your skis. If you want a race like feel out of your ski boots, without the ultra-narrow fit, the Salomon X-Max 100 will be a great option.
