I went TTS on my sz 10.5 royal pair of 312 legacys and they run a bit snug on the toebox. I would recommend a half size up to be honest. I'm going after SZ 11's now for the other colorways.
Yes, legit. I wouldnt post them if they weren't. Kicksdeals posted them as well if you dont believe me and they only post legit sites... http://kicksdeals.com/2016/08/24/jordan-i-retro-high-og-black-black-white-2/

Shipping costs can vary alot from site to site on euro sites, but i'd say 190 to 220 shipped would be a good average. I was lucky to score a few pairs under $200 shipped
