I bought a size 8 but I normally wear an 8 1/2. My left foot is bigger than my right foot. There is about 1/2 inch give in the right front toe area and about 1/4 inch give in the left toe area. Should I have gotten an 8 1/2? The shoes feel ok but feel warm on my feet. If I was in a store I would have tried both sizes on and decided. What do you think?
