Non-slip EVA sandals, black, size M. Brand new, unused. - Color: Black - Material: EVA - Size: M - Usage: Indoor/outdoor sandals - Features: Sandals that can be used both indoors and outdoors. The sole uses synthetic rubber and is designed to be non-slip. They are made a bit larger (for high insteps) and come with cup insoles for excellent comfort. There are no holes on the surface, so water will not penetrate from the front even in wet areas. They have a back strap to securely hold your feet. Thank you for viewing.
