The Salewa Women's Alp Flow Mid GTX Hiking Boot boasts the most innovative features found in boots. Gore-Tex's Surround midsole offers waterproofing superior to the competition, with a laminate that wraps around the entire boot. Unlike most waterproof boots, Gore-Tex Surround includes a specially-perforated footbed to provide true breathability underfoot, resulting in an entirely comfortable hike whether you're trekking in hot, muggy weather or cold, wet weather. Salewa paired Gore-Tex's Surround with Gore-Tex's Extended Comfort for even more waterproof breathable protection. The Alp Flow also features Salewa's 3F System Evo for a surprising amount of flexibility and mobility in a supportive mid-cuff boot. Ballistic mesh makes the upper very breathable and durable, and Salewa added nubuck leather reinforcements and a 360-degree rubber rand for rock protection. Climbing-style laces give a snug fit from toe to foot. Vibram's Hike Apparoach sole gives the grip, flex, and durability that's ideal for the most demanding excursions. · Gore-Tex Extended Comfort · Gore-Tex Surround midsole · 3F System Evo · Ballistic mesh upper with nubuck leather reinforcements · 360-degree rubber rand · Climbing-style laces · Vibram Hike Approach sole · Item #SFW001T Tech Specs Upper Material ballistic mesh, nubuck, 360 rubber rand Waterproofing Gore-Tex Extended Comfort Closure climbing-style lace Last 3F System Evo Midsole Gore-Tex Surround Sole Vibram Hike Approach Claimed Weight 1 lb 2.1 oz Recommended Use backpacking, hiking & camping Manufacturer Warranty |
