The Columbia Women's Powderhouse Titanium Omni-Heat 3D Outdry Winter Boot is designed to keep you warm in harsh, rugged winter conditions. A waterproof leather upper reliably fends off moisture to keep your feet warm and comfortably dry, and Columbia's Omni-Heat reflective lining and insulation ensure that none of your precious warmth escapes. In addition to being warm and completely weather-resistant, the boot is comfortable, too, with a cushioned, supportive EVA midsole for plush stability, and is finished off with a durable Michelin rubber outsole to give you confidence-inspiring grip on slick winter terrain.
