Features:

• The most minimal shoe in the Topo line, built for daily runs, up-tempo workouts and gym work.
• 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.
• The collapsible heel counter allows the shoe to pack flat into a gym bag or for travel.
