I can’t say that I have ever purchased a pair of shoes online, since I am so picky about the fit. But this shoe had such good reviews that it was hard to pass up. They feel WONDERFUL!!! It's about time a good pair of running shoes have some arch support. These shoes are extremely comfortable and don't even need to be broken in. Reviews said they seemed to run small, maybe by half a size. Great shoe, Great price. I definitely recommend purchasing these!! You’ll love them too.
