How to use: Just lace up these shoes and you're ready to hit the road for your daily runs or long - distance training. They're suitable for different running paces, whether you're going for a fast sprint or a slow, steady jog. Notice: Make sure the laces are tightened properly to get the best support from the FantomFit technology. Also, if your feet tend to get sweaty, consider using moisture - wicking socks. Maintenance: After each run, gently wipe off any dirt or mud on the shoes. Let them air dry naturally, away from direct heat sources. Don't machine - wash or dry them, as this may damage the foam and the upper material.
