How to use: Slip your feet into the sandals and adjust the hook - and - loop straps and ankle buckle strap to your desired tightness. For a customized fit, you can replace the insole with orthotics. Attention: Don't wear these sandals in extremely wet conditions for a long time as it may damage the leather. Maintenance: Clean the leather upper regularly with a soft, damp cloth. Let them dry naturally away from direct heat. If the insole gets dirty, remove it and wash it gently.
