Be very careful - these t-shirts are much narrower than other size 13D New Balance sneakers. Not as stifling as the 913 (skate), but not as roomy as the 420 (skate, comparison photo attached) or even the 996 (tennis). The materials seem really nice and it's a great green color - the photos don't do it justice. I will try to gift this pair and try my luck with 13 watts.
