Using these insoles is easy. Just take out your old insoles and put these new ones in your shoes. Trim them according to your shoe size if needed. When it comes to maintenance, you can remove them from your shoes regularly and let them air dry to keep them fresh. Be careful not to wash them with very hot water as it may damage the cushioning foam. Also, avoid putting them in direct sunlight for a long time. With proper use and care, these insoles will serve you well and keep your feet comfortable.
