ORiental TRaffic Sport Sandals - Color: Black - Size: M - Design: Strap Sandals - Sole: Rubber Sole - Features: Adjustable Straps - Retail Price: ¥6600 Thank you for viewing. I purchased these in 2021 and have kept them in storage without ever using them. The soles appear whitish, but this is not mold; it's likely due to the aging of the rubber material. Please refrain from purchasing if you are concerned about this. Please understand that these are items stored at home before purchasing. There are no smokers or pets in the home.
