Home washed! The entire shoes, inside and out, have been washed with a detergent that claims to disinfect and deodorize. adidas SUPERSTAR slip on Adidas Superstar Slip-On Color: White Size: US 10 1/2, 27.5cm ※Normally, US 10 1/2 would be 28.5cm, but this is labeled as 27.5cm (JP). The CN (China) size is 26.5cm, so I believe this is correct. The fit also felt like a usual 27.5cm. ※I washed them using powdered oxygen bleach, but some blackening remains on the inner lining. It's slightly more noticeable on the right shoe. Please refrain from purchasing if you are concerned about these points. This is a slip-on version of the familiar Superstar, making it easy to wear. There is almost no wear on the soles, and there is no stretching of the rubber, which is common with this product.
