Adidas Samba RM in Core Black. I purchased these from the Adidas official online store when they were released. The midsole has been changed to a material developed for jogging and is covered with blue translucent rubber. They have been worn only a few times, and there is minimal wear on the heels, but there is some tearing on the inside of the heels, possibly because I wore them with the laces loose. They are being traded for around 60,000 yen on sneaker trading sites.
