Bought a used pair, size 13 US/12 UK/47 EUR and they are in excellent shape. Trax-XT5 rubber. It is my understanding that they were only used in the gym, and they look it. They are just too small for me. I would like to trade them for a similar pair in similar shape in a larger size. I normally wear a size 12.5/13 depending on the shoe/boot, but these feel like they are closer to a normal 11 size... Pics are from the seller, I can try to get better ones if desired.
