Using these Shimano cross - country shoes is a breeze. Just adjust the BOA® L6 dial on the instep strap to get a comfortable fit for your feet. When riding, the shoes' design will help you transfer power efficiently and keep your feet stable. As for maintenance, after each ride, use a soft brush or cloth to clean off dirt and debris from the outsole and upper. Don't use harsh chemicals as they might damage the materials. Store the shoes in a cool, dry place. When it comes to choosing spikes, think about the terrain and your riding style. If you're on a muddy track, go for longer spikes. For smoother surfaces, shorter ones will do the job. And always check the spikes regularly for wear and tear and replace them when needed.
