Using these shoes is easy. Just open the velcro strap, slip your foot in, and close the strap to get a perfect fit. When you need a more customized fit, you can play around with the forefoot inserts - add, layer, or remove them as you like. If you have specific foot support needs, take out the Active Comfort footbed and put in your own orthotics. As for maintenance, keep them clean by gently wiping with a damp cloth. Avoid using harsh chemicals as they might damage the vegan - friendly materials. Also, store them in a cool, dry place when not in use to keep them in good condition.
