The Salomon S/Pro Alpha 100 Ski Boots offer premium performance and unrivaled fit. With a friendly and approachable 100-millimeter flex, the S/Pro Alpha 100 is an ideal boot for developing skiers looking for high performance and a medium to wider last of 98-104 millimeters. This wide, comfort-focused last can be heat molded using the custom heat molding process by your local boot fitter. Salomon's proven heat molding process makes boot fitting most feet quick and easy - the latest Polyurethane shell version is even quicker to mold than before. The thinner wall construction and new shell materials allow the foot to be closer to the shell and provide enhanced sensations, more power and direction energy transmission. This alleviates pressure on the top of your foot and ensures stronger heel lock without putting unnecessary pressure on your feet. A great performing boot is all about having a nice tight fit, with no wiggle room or “slop” so when you transmit power from your boot, it goes directly into the skis. If you want to be the “Alpha” dog in your rat pack, then the Salomon S/Pro Alpha 100 Ski Boots will keep you at the top of your game while allowing you to progress with your all –mountain skills with comfort and performance that you will never outgrow.
