Because my feet are narrow, the laces would loosen even when tied tightly. I used these shoes 3 or 4 times before buying a new pair, which I'm now using. I'm selling these. I tightened the top laces quite a bit, so the area with the size information is cracked from rubbing. There's also some black marks on the side. I bought a new pair right away, so I'm selling these. I think they're in good condition, but please check the pictures. asics 23.0cm Black x White No box
