How to use: Just put on the shoes, adjust the laces for a comfortable fit, and you're ready to hit the road or track. These shoes are great for running, whether it's a casual jog or a serious training session. Attention: Since the 6mm drop is approximate, don't be too concerned if there's a small difference. Also, make sure the laces are tied properly to avoid tripping. Maintenance: To keep your shoes in good condition, wipe them with a damp cloth after each use. Let them air - dry naturally, and avoid putting them in direct sunlight or using a dryer. This will help maintain the integrity of the synthetic/mesh material and the FuelCell foam.
