Previous reviewers were right, these shoes run small.
About one size smaller than my usual shoes.  I have smallish feet but usually buy a 7 1/2 which fit perfectly with socks.  I bought the 7 1/2 shoes figuring I wouldn't have the same issue as other reviewers have mentioned.  No such luck:)  These fit like a 6 1/2 would & without socks.
Besides the small fit, I absolutely love these shoes!  They are comfortable in every aspect you'd expect from an athletic shoe.
I am returning this pair (love Amazon return policy:)  and have just ordered 2 new pair of 8 1/2 shoes in different colors.
