The Tahoe GTX Hiking Shoe uses AS-Tech technology to add structure and torsion stability to a low-cut build made for fastpacking and speed hiking. Gore-Tex Extended Comfort Footwear and a TPU-reinforced polyester upper protect against water and abrasion without adding bulk. An Asolo Cross outsole with Sigma Grip compound grips rugged, uneven terrain, so the shoe stays composed even when the trail gets technical. What Our Gearhead(R) Experts Are Saying:"I've moved fast over loose, rocky ground in these and never felt the shoe twist underfoot. AS-Tech holds the structure exactly where a low-cut shoe usually gives it up."
