Synchro Alpine Touring Boot

La Sportiva's Synchro Sku Boot is kind of like an ambiguous image—like the vases that look like faces—in that some ways it looks like a ski mountaineering boot and in others it looks like an alpine touring boot. One thing's for sure, you won't feel like turning around when your high stoke spontaneously changes casual tours into skimo epics. Its roomy 102.5 last works with the thermo-moldable liner to create a comfortable housing for your foot as you two brave the steeps in search of a downhill that's worthy of this boot's rugged rowdiness.

A carbon-infused vertebra makes the Synchro La Sportiva's stiffest boot ever built, meaning this boot is just as much a hard-charger as it is an easy-hiker. La Sportiva made the rest of this boot out of Grilamid for rigid durability that still weighs around three pounds per boot. The Vibram rubber sole has the traction necessary for rocky summits, and this boot is compatible with all tech bindings.
