I'm trying to buy some online and I don't know if they run in men sizes or what. Meaning like Nike for instance, the dunks I buy are in men sizes but they are women shoes. So I wear a 7 in women and a 5.5 in men so what size should i get for recs the 5.5 or the 7? Please only answer if you know. I live in Germany right now and they don't sell them here so I can't just walk in a store and try them on else I would do so! Thanks in advance!
