To use these shoes, simply adjust the three hook - and - loop straps on top to get a comfortable fit. Put your feet in and you're ready to go. When it comes to maintenance, you can clean the nubuck upper gently with a soft brush. Avoid getting the shoes too wet as it may damage the leather. If the footbed gets dirty, you can remove it and clean it separately. Also, store the shoes in a cool, dry place when not in use to keep them in good condition.
