To use these shoes, just slip your feet in and use the speed - lacing system to quickly secure them. If you want, you can also use the classic laces provided. When you're running or walking, enjoy the soft landings and powerful push - offs the CloudTec® cushioning offers. For maintenance, it's best to keep them clean. You can use a soft brush and mild soap to gently clean the mesh and other parts. Avoid machine - washing as it may damage the taped reinforcements. Also, store them in a cool, dry place away from direct sunlight to keep the materials in good condition.
