Natural running enthusiasts and gym-goers, this minimalist shoe for working out is for you. With the newly refreshed ST-5, we added a ZipFoam™ midsole and lowered the zero drop platform to just 14 mm for a close-to-barefoot experience, with just enough cushioning to keep you comfortable. The sleek upper features a recycled mesh and delivers a secure, well-ventilated fit. If you prefer a minimal underfoot experience for everything from running, to gym work, to casual wear, look no further than the Topo Athletic ST-5.
