I bout these for the tread, great tread! I plan on working out in these, I was amazed how light these are and color is great. I'm usually an 8.5 - 9 and I ordered a 9, good thing I did, these are very sung, if any smaller they would not fit. The are a little tight around towards the toe, but still feel great. Definitely recommend but order at least a half size up from you normally are!!!
