Using these shoes is a breeze. Just slip your feet in, and the elastic on the instep will stretch to fit your foot comfortably. You can wear them barefoot in summer for a cool look or pair them with tights in winter. When it comes to sizing, remember they run a bit small, so it's a good idea to choose one size bigger. For foot comfort, you can remove the insole and add your custom orthotics if needed. To keep them in good shape, clean them regularly with a soft leather cleaner. Avoid getting them wet in heavy rain or soaking them in water. Also, store them in a cool, dry place when not in use.
