How to use: Simply slip your feet into the shoes. The zonal knit material makes it easy to wear. Tie the laces if you want a more secure fit. When running, the shoes' design will help you with a smooth forward - rolling motion. You'll notice softer landings and powerful take - offs. Note: These shoes are designed for road running, especially on hard surfaces like concrete in the city. Avoid wearing them in extremely muddy or wet conditions as it might damage the materials. Maintenance: After each run, use a soft brush or cloth to clean off any dirt or dust. Let them dry naturally in a well - ventilated area. Don't put them in the dryer as high heat can damage the foam and other components.
