Men's US 10.5 is UK 10 and Women's 10.5 is UK 9 - a total size difference! I ordered 2 sizes separately. Men's Adidas Supernova sneakers (these are great shoes for 10k) but one of the pairs that arrived was women's shoes, not men's, and differed in size. I sent back the male version and they sent me the smaller female version again. This is what you would expect from a third party, but this is from Adidas!
