Lightweight mesh design sneakers, excellent breathability and comfortable to wear. Barefoot shoes. - Brand: SAGUARO - Color: Black/Green - Sole Material: Rubber - Design: Mesh/Lightweight - Size: EU39 / 24.5cm Thank you for viewing. I bought these for the gym, but they felt loose, so I'm selling them. I am 24.5cm with a B width and low instep, so I think they will fit people with normal foot widths without any problems. I purchased them in September and only tried them on indoors with socks, so they are unused. They have been stored at home and are in good condition, but please check the photos before purchasing. There are no pets or smokers in the house.
