Bought for Zumba. Took the advice & got 7 1/2 even though Im a wide 7. I definitely could have gotten away with the 7, because these shoes are pretty wide. No sad feet after an hour of zumba & I found it was 150% easier to do the sliding/quick moves than with my old running shoes. I love them!

Update:09/03/2013 Wow, has it really been almost 2 years? That is crazy! The good news is, these shoes are still going strong! It doesnt surprise me, because I only wear them once or twice a week, but that is still impressive. I love Ryka as a shoe brand. Awesome shoe.
