The shoes run a tiny bit large (i wear 9 or 9.5 but on these ones, the 9 is just a tad big.  But the shoes are super light, very comfortable, will give me at least a few years of wear and didn't require a break-in period.

The front part of the sole is a bit slippery but after a few wears, it got "grippier."  I'll tell ya, unless you're a fancy person who needs to have $400 pradas, these shoes are going to make you happy.
