Description

The Oboz Sawtooth Ascent Mid Waterproof is a women's hiking boot built for day hikes and shorter treks on rocky trail. Its B-DRY waterproof, breathable membrane blocks moisture while letting sweat escape, so feet stay dry and comfortable. The Vibram XS-TREK EVO outsole gives consistent traction across a wide range of surfaces and conditions. Inside, the triple-density O FIT Insole adds cushioning and medium-to-high arch support, and the women-specific fit pairs a snug heel with a roomy toe box.

How to measure: stand on a piece of paper and mark the back of your heel and the tip of your longest toe, then measure the distance in centimeters and match it to the closest CM value in the chart.

Fit notes: Oboz footwear is built with a supportive arch that connects a roomy toe box to a sculpted heel pocket. Styles come in two fit types - Generous, with extra room for toe splay and foot swelling on long hikes, and Athletic, which conforms to the foot for a nimble, precise feel. Nearly every pair includes Oboz's O FIT Insole, shaped to the last and size of the footwear. Fit can feel different style-to-style, so Oboz recommends getting your feet measured often and trying a range of styles.
