These are lightweight and breathable NIKE sneakers. I bought them about two years ago, but they have been stored unused. They have been stored in a box at home, so there are no stains, but I have a cat at home, so there may be some cat hair attached. - Brand: Nike - Model Name: Air Zoom SuperRep 3 PRM - Size: US7.5 - Color: White/Volt - Material: Synthetic fiber/Synthetic resin Thank you for looking.
