HOKA's Speedgoat 6 is a technical terrain-focused shoe that's just at home in urban settings as it is on the trails. The upper is constructed from lightweight woven materials, while a dual-sided gusseted tongue pulls cues from long-distance runners and an internal support chassis keeps everything snug yet structurally robust. Underfoot, a Vibram Megagrip rubber outsole houses a revised lug orientation inspired by the hooves of mountain goats. This workhorse for technical terrain was refined with a breathable woven textile upper, foot-hugging internal chassis, plusher dual gusset tongue, and revised lug orientation inspired by the hoof of a goat. Upper: Textile & Synthetic. Sole: Synthetic.
