These sandals are easy to use. Just slip your feet in and you're ready to go! When it comes to choosing the right size, make sure to measure your foot length from heel to toe and match it with the size chart. For daily use, you can wear them for walking, running errands, or a casual day out. As for maintenance, wipe them with a soft, dry cloth after use to keep them clean. Avoid getting them wet for long periods as it may damage the split leather. If they do get wet, let them dry naturally away from direct heat. This will help keep your sandals in great shape for a long time.
