The Salomon Crosstrak Waterproof Boot is designed to keep us hiking year round, whether we're trekking snow-covered trails or hopping over puddles of slush on a chilly spring afternoon. The adv. DRY waterproof membrane shields us from wet, heavy snow, keeping our socks dry and comfortable as we push toward snow-capped summits. The adv. WARM synthetic insulation ensures our feet stay warm, and the fleece collar keeps cold air from seeping in and turning our feet into ice blocks.
