Using the Ergon Solestar IP Touring Series insoles is easy. Just remove your existing insoles from your cycling shoes and place these new ones inside. Make sure they fit properly and align well with the shape of your shoes. When it comes to cycling, these insoles will help you pedal more efficiently and comfortably. For walking, they still offer great support. As for maintenance, you can gently clean the insoles with a damp cloth if they get dirty. Avoid using harsh chemicals or putting them in the washing machine. Also, make sure to let them dry completely before putting them back in your shoes. If you notice any signs of wear and tear, it might be time to replace them to keep getting the best performance.
