The Topo ST-4 brings a lightweight, minimalist experience for you to run and lift weights naturally. A shoe that excels at both running and in the gym, the Topo ST-4 gives you a minimal, flexible fit with a zero heel-to-toe drop, so you can feel the ground throughout your workout. It features the signature Topo fit with a wide toe box, so your toes can splay and a snug midfoot and heel to give you a great lockdown. Plus, a new OrthoLite® footbed gives you long-term comfort and odor resistance. A cool and breathable mesh upper has printed overlays and an internal skeleton lining to keep the fit secure and prevent your foot from sliding off the cushioning during side-to-side movements or speedwork. A relaxed heel construction with no built-in heel counter provides for a more natural fit and makes these shoes a great travel companion because they can essentially pack flat. One of the most minimalist shoes on the market, the Topo ST-4 is so comfortable you will feel like you aren’t wearing shoes at all.
