To use these shoes, simply put your feet in and use the Boa L6 dial to adjust the fit until it's comfortable. They're great for off - road bike riding, whether you're racing or just enjoying a ride. When it comes to maintenance, keep them clean by wiping them with a damp cloth after use. Avoid exposing them to extreme heat or cold. Also, check the midsole and the upper regularly for any signs of wear and tear. If you notice any issues, it might be time to replace them. And always make sure the fit is right before you hit the trail to get the most out of your ride.
