Fits on my 2x2 (Fitness Reality 810XLT) rack with 1" holes. Love the fact that the bottoms of the shoes are rubber so there is no slipping. I ordered the black in size 7. Good mic, good price. Do not follow the size chart provided. Nice irony at the end in a sublime speech about dictatorship, which of course describes the US to a tee. (For those curious I was listening through a Fiio E17 connected to my iPhone digitally using Apples Camera Connection Kit). The drawstring i could live without and may find a way to yank it out because it does try to tighten up at times. A little strange, the colors match the picture. I am a mechanical design engineer and consider this an excellent product and a great value for the price.
