The Oboz Sawtooth Ascent Mid Insulated Waterproof is a men’s winter hiking boot built for cold-weather adventures, from frozen trailheads to deep-snow backcountry days. It pairs a waterproof, breathable B-DRY membrane with lightweight 200g insulation, so you stay dry and warm without the boot feeling stiff or bulky. A Vibram ice-ready outsole keeps you planted on packed snow and icy paths, and the mid-cut collar adds the ankle support you want once the trail turns slick. In the Black Sea colorway, it’s a solid pick for hikers and backpackers who need one boot that handles winter hiking, snowshoeing approaches, and everyday cold-weather wear.
- B-DRY waterproof, breathable membrane blocks out slush and snowmelt while letting sweat vapor escape, keeping your feet dry in changing winter conditions.
- 200g Freeze Guard insulation adds warmth throughout the interior without piling on bulk, so the boot stays nimble on frozen trails and deep snow.
- Vibram Ice Trek traction outsole is tuned to grip very cold, icy, and snowy surfaces for dependable footing on unpredictable winter terrain.
- Suede leather and closed-mesh upper with no-sew TPU underlays and protective toe and heel caps stand up to rough, demanding winter routes.
- Fleece-lined collar adds a layer of warmth and comfort right where your ankle meets the boot.
- Triple-density O FIT insole works with the KINERTIA EVA midsole for lightweight cushioning and support mile after cold mile.
- Mid-cut profile adds ankle stability and protection you don’t get from a low-top hiking shoe.
