Using these Shimano GR903 shoes is easy. Just lace them up like your regular shoes and you're ready to hit the off - road or go for a gravity ride. Whether you're on an e - bike or a regular bike, these shoes will offer great support. When riding, make sure the laces are tied tightly to avoid any tripping hazards. As for maintenance, after a muddy or wet ride, rinse the shoes with clean water to remove dirt. Let them dry naturally in a well - ventilated area, away from direct heat sources as high temperatures can damage the materials. Check the soles regularly for excessive wear and tear. If you notice any significant damage, it might be time to replace the shoes.
