I bought these shoes to wear to Zumba and have found them to be a light weight and comfy slip on shoe, perfect for the fast turns and steps in Zumba. Several other reviews I read said that you should go for a size higher than you normally wear, but I don't think this is necessarily true. I usually wear a 6 and bought a 6.5 (as there was no size 6 available) and to be honest, it's a little bit too long. If you have very wide feet, then perhaps going for a bigger size might be better, but I mean *very* wide! The company I bought them from (Dancing in the Street), converts the size from American to British for you.
