Altra Mont Blanc Boa

Built for long miles on technical trails, the Altra Mont Blanc BOA takes the fast-and-cushioned Mont Blanc platform and replaces traditional laces with a precision dual-dial BOA Fit System. The result is a more dialed-in, locked-down feel when footing gets sketchy, while still keeping the roomy, natural toe splay Altra is known for. Underfoot, the lively Altra EGO MAX midsole stays comfortable deep into ultra-distance efforts, and a grippy Vibram Litebase outsole helps you stay confident on wet rock, dry dust, and everything in between.
