Thank you for looking! These shoes are wide, and the straps use Velcro. They also have elastic cutouts, making them easy to put on and take off. They are unused, so they're also suitable for indoor wear. Size: 23.5cm Width: 4E Color: Off-white Heel height: Approximately 3.5cm I only tried them on indoors. I'm selling them because I haven't had a chance to wear them for a while. For some reason, there are small holes on both heels. Please check the fourth photo! Although they are unused, they have been stored at home for a long time, so please understand this before purchasing.
