The Topo Athletic Runventure 2 is a lightweight 0-drop trail shoe that’s currently the most comfortable shoe I own. Built for all-day wear, the upper is airy and breathable with a seamless socklike neoprene heel collar. The responsive midsole has a 15mm stack height that provides just enough cushioning for longer days on the trail. For the outsole, Topo uses a low profile lug design that’s best suited for hard pack and less technical outings.
