I work 12 hours days, and am on my feet for about 10 of those hours. I read the reviews, and bought the shoes a half size larger. They fit perfectly. The other reviews are accurate. These shoes are very light, offer superb arch support, and do tend to run a half size too small. After a couple of uncomfortable days breaking them in, I can't see myself wearing anything else to work. As long as Avia keeps making them, I'll keep buying them.
