Bought three pairs of these not too long ago from woot. Two pairs of black and pair of grey. The two black pairs, though stating the same size fit vastly different. One was decent, the other felt like it was a mislabeled small. The grey fit well, but started to fall apart at the seams fairly quickly (Less than two washes). I would say the quality control on these was lacking in a big way and I would pass pass pass.
