On Cloudmonster used US8 There is a crack in the cushion on the inside of one side, but it does not affect the use at all. You can still use them, but I am selling them because I bought new sneakers. Recommended for those who understand second-hand goods and those who want to try wearing Monster shoes. The cushioning is excellent and your feet will not get tired easily.
