Merrell Siren 4 Thermo Mid Zip Waterproof Boots - Women's

Frost-crusted trails and slushy shoulder-season switchbacks require gear that prioritizes movement over bulk. The Merrell Siren 4 Thermo Mid Zip Waterproof is built for those who refuse to hibernate when the mercury drops, utilizing a refined zipper system that lets you transition from a trailhead coffee to a frozen summit push in seconds. Beneath the sleek mesh and TPU upper, 200 grams of insulation trap heat without sacrificing flexibility, while the fleece-lined interior maintains a soft, reliable climate for your feet. Whether you are navigating jagged, icy patches or pushing through packed snow, the Vibram Icetrek outsole bites into slick surfaces with confidence. Every step is cushioned by a FloatPro Foam midsole, and with a protective rock plate integrated into the base, the jagged edges of a winter path disappear beneath your stride.
