These men's running sneakers are perfect for advanced runners doing half marathons on hard courts. When you first get them, make sure to measure your feet properly and pick the right size according to the size guide. Just put them on like any other lace - up shoes. During your runs, the breathable upper and air sole technology will keep your feet cool and provide great stability. After use, remove the insoles and let them air dry. You can clean the upper with a soft brush and mild soap. Avoid using harsh chemicals as they might damage the PU and EVA materials. Store them in a cool, dry place to keep them in good condition.
