I love Asics and have owned more pairs than I can count. I was looking for a pair of shoes for Zumba and ordered the Gel-Rhythmics. I was a bit disappointed in this style. I have always worn a size 9 so that is what I ordered. I have normal arches and a medium width foot. When I tried on the shoes they were way to small. My foot barely fit in the shoe. Sorry I can't give a description on how they were to work out it, I couldn't even get that far! I'm not saying they are a bad shoe to work out in, I would just get a 1/2 a size or even a full size larger than you normally wear if you are looking to try this shoe.
