Using these shoes is easy. Just slip your feet in and use the speed - lacing system to quickly secure them. If you like the traditional way, you can use the classic laces that come in the box. When you're out running or walking, you'll feel the soft landings and powerful push - offs. For maintenance, clean them regularly with a soft brush and mild soap. Don't machine - wash them as it may damage the materials. Store them in a cool, dry place away from direct sunlight. Also, make sure to check the soles regularly for wear and tear, and replace them when needed.
