Using the Mad Rock Flash 2 climbing shoes is straightforward. First, use the double pull loops to easily slip your feet into the shoes. You can also hook a carabiner through the loops if you want to carry them around conveniently. Once on, adjust the 2 - strap closure to get a snug fit. These shoes are great for all - round climbing, whether you're on an indoor wall or an outdoor rock face. When it comes to maintenance, after each use, wipe off any dirt or debris with a dry cloth. Avoid getting them wet as much as possible, but if they do get wet, let them air dry naturally. Don't expose them to direct heat sources like radiators. Also, check the sole and midsole regularly for any signs of wear and tear. If you notice significant damage, it might be time to replace them.
