I have always purchased Asics sneakers because you can wear them all day long and your feet don't hurt. I wear a size 7 but always but a 7-1/2 in Asics. These sneakers fit but they are tight on top of the foot. I have taken the lases out thinking they were too tight, not the problem. I don't know if I would order an 8, they would be to big. These sneakers would be great if they were not tight.
