Using these Olive Shimano SH - GE900 MTB shoes is easy. First, use the BOA Fit System to adjust the shoes to your foot for a secure fit. When riding, you'll notice the great grip on the pedals thanks to the ULTREAD GE rubber compound. For walking, the same rubber gives you good traction. On descents and corners, the shoes offer excellent control. As for maintenance, after each ride, wipe off any dirt or mud. If they get really dirty, you can gently wash them with mild soap and water. Let them air - dry. Don't put them in the dryer as it might damage the materials. Also, check the BOA Fit System regularly to make sure it's working properly. And remember, these shoes are made for MTB riding, so use them on appropriate trails for the best performance.
