Columbia SAPLAND II WP OMNI-HEAT INFINITY Sapland II Waterproof Omni-Heat Infinity YU4541-008 Snow Boots Waterproof Stratus Color: Stratus Size: 27.5 The tall "SAPLAND II WP OMNI-HEAT INFINITY" snow boots are recommended for those who prioritize peace of mind, offering high heat retention and protecting feet from snow and cold. The liner uses Columbia's unique thermal insulation technology, "Omni-Heat Infinity," which significantly improves heat reflectivity compared to the original Omni-Heat. The outsole, a key feature of the Sapland collection, uses Vibram Arctic Grip. This Vibram original sole was developed to allow safe walking even in severe conditions with snow and ice. It doesn't harden even at -20°C, and the lugs (protrusions) with fine protrusions utilize friction to provide stable grip on both dry and wet ice. In addition, the midsole and insole use lightweight and cushioned materials, maintaining a comfortable fit even during extended use. The speed lacing, heel tab, and side zip-up fastener make it easy to put on and take off even with gloves on. The upper uses Cordura fabric for excellent durability and is waterproof, allowing you to wear it with confidence in any weather. This item allows you to live comfortably even in unexpected winter road conditions, such as icy roads and snowfall, and in harsh cold weather!
