CrocsClassic Mega Crush Clogs | Platform Shoes unisex-adult Clog

should i pick the brand size that match with the actual us size?

Love these but my middle toes on 1 foot keep falling asleep..?? I do have VERY flat feet. Insert advice? General advice....TY!

I wear a size 6 in the classic women platform clog, should i size down or stay at a size 6?

Are they real ?
