Topo Shoes employ a split-toe, anatomically-optimized design that captures the feet's natural shape and allows the toes to be as comfortable as possible. And while they provide more underfoot protection than most lightweight minimalist shoes, they're still able to offer superior ground feel and flexibility. Topo shoes are made from soft microfiber and breathable mesh and are available in three variants (with each made for varying levels of physical activity): RT (Roadtrain), RX (Prescription), and RR (Road Race).
