The Salomon S/Pro MV 90 Ski Boots undergo a very minor name change (they realized every alpine Salomon boot was called S/Pro and wanted to call out the medium volume) but the best-selling fit, design, and even colorway remain. For average width feet and many wider ones, the S/Pro Custom Shell HD fit is the gold standard, and that trend isn't slowing down. The 90 flex continues to be the best-seller in the range and is suitable for most intermediate to advanced skiers. Features: Fit Last: 100 mm – An average last for that can be expanded to accommodate wider feet. Custom Shell HD – Salomon's proven heat molding process makes boot fitting most feet quick and easy - the latest Custom Shell HD 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.
