My feet are about a 5.5, and I ordered these in size 6! They fit amazing, and are definitely the coolest shoes I own. Only issue is that the bottoms are very smooth and quite slippery, but other than that, I love them.
I originally ordered them in a size 6 but my feet are wide so they weren’t comfortable so i got a size up, absolutely perfect. Deliver was so fast especially considering what’s going on at the moment, got my shoes within 4 days of ordering them!!!!! Brilliant, would 100% shop here again.
