I'm a size 12 and TTS is perfect for me. .5 would probably work for me since the material stretches but would almost maybe be to small for myself. All depends on your foot.
I'm also a 12 in most Nike's and I get a 12 in the racers. They do fit a tad smaller than normal but they stretch some. I don't run in mine so I go TTS, but if I did then i would probably get a 12 1/2. I enjoy the fitted feel of them.
I'm 6'2 195lbs and the aw77 was just long enough to wear but, the sleeve length was to short for me. If I moved my arms at all the sleeves rode up my arm some, which I found annoying. Wind runner is longer in the body, and has longer sleeves that fit perfect. Both have a slight fitted fit to them.
