While I have the Nike React Vision (in white and gray) which are similar if not almost identical, and in both I got size 44 from different stores, in this shoe that I received and tried on, not only do they come off my foot, but they are so far in length that I would need to get size 42 2/3... I don't know what's going on... while they are very nice with a nice soft sole, I found that their materials are inferior and the tongue of the shoe simply does not exist... it's a thin piece of nylon that shocked me... essentially you don't notice it and it feels uncomfortable... and I give it a 3 out of 5
