The versatile Sawtooth Mid is just as comfortable thru-hiking the AT as it is exploring your local trails. The outsole shape promotes a natural rolling motion when the going is smooth and has toothy high friction side lugs for when the trail turns nasty. The upper is both waterproof and breathable with a 3D molded heel counter for superb heel fit The Upper is made using Waterproof Nubuck Leather & Highly Abrasion Resistant Textile. The BFit Deluxe Insole stabilizes arches, protects high-impact zones, and costs nothing extra. They mold the heel counter in 3D, making it extra durable against collapse. Their proprietary BDry membrane blocks water from wet trails while wicking sweat away.
