They're way too narrow for me. I like a wider shoe. The Brooks racer with the slight added stability (I'm terrible with model numbers, I think it was the t6, but maybe that was the one without the added stability) fits nicely for me because the forefoot is wide. However, I simply could not wear Inov-8s. I've tried a few different models and my foot actually hangs off the sides of the sole.
So, if you have wide feet, not the shoe for you. At least until they come out with widths.
