These run VERY small. I wore a pair of size 8.5 Pumas (an older EvoSpeed) for a few years, so I ordered these in the same size--I could not even get my foot in the shoe! I actually ended up going to a soccer shop and purchasing a men's version of the shoe in a size 8 (normally I wear a men's 6.5-7). I love Puma indoor shoes, but the sizes have changed dramatically.
