A tried and true big mountain expedition boot that refuses to come up short, the Salomon Men's Synapse Wide Snowboard Boot is destined for all mountain success. Built for serious big line ripping, the Synapse has a stiff flex to give you the response necessary in no fall zones and a slew of features that keep you going through intense hikes and long approaches. It also has a widened mid and forefoot zone, allowing you to ride comfortably without having to sacrifice fit and performance by sizing up. The PowerLock Pro lacing system offers a criss cross locker on the tongue and anti catch hooks on the upper to deliver a truly powerful and easy entry system that handles anything the mountain sends your way. With a Full Custom Fit thermo moldable liner, the Synapse ensures just the right fit, while the Heel Grip reinforcements at the heel helps grip your socks to the inside of the boot for an increased heel hold. A Gold 3D Exhale liner uses perforated insole and outsole mesh channels to keep your feet cool and comfortable when things start to heat up. The Ortholite C3 footbed is composed of a high density base, memory foam layer, and an EVA heel cup for maximum comfort, fit, and overall support. With hiking boot inspired rubber pads, the Hike Plus outsole delivers maximum dampening and high traction grips to aid you in your endless alpine pursuit to earn your turns. The liner is washer friendly so you don't have to deal with the season long stink.
