I normally wear 7.5. In fact I have this style shoe from
Roxy last year in a 7.5. But the sizing seems to have changed this year as this shoe in a 7.5 is at least a half size too small. And there is a seam on top of your big toe which rubs horribly, not sure it would even be comfortable with socks. Wanted so bad to like them, as they are cute... just too uncomfortable.
