The Moab FST Ice Thermo from Merrell is a great mens winter ltr boot that is waterproof and insulated. The uppers are made from leather and textiles which supports the foot and feels great on. The Merrell M Select DRY technology seals water out ensuring your feet stay dry no matter what. The fleece and M Select warm lining with 100 grams of insulation keeps your feet warm while the bellows tongue keeps debris out. A traditional lace closure makes these waterproof mens walking boots easy to get on and off and to adjust so you get the best fit possible. A moulded nylon arch shank in the sole and the Merrell air cushioning in the heel provides superior comfort and support. The outsole is Vibram's Arctic grip outsole with a 5mm lug depth which is durable and provides great grip even in extreme conditions and completes this mens winter hiking boot perfectly.
