I always get worried buying shoes online, but these were such a great deal that I had to check them out. Overall, they fit true to size and are very comfortable & light weight. I'm very happy with my purchase!

Update: Not as happy with these shoes after using them for a few months. Although they do fit in general, they must not be a perfect fit for my foot. The balls of my feet have been developing blisters when I run anymore than 2-3 miles, even when I'm using thicker socks. It's been a major issue and has caused me to shorten my runs significantly. I did get a great deal on them, but now i'm trying to save up for a better pair ... so I didn't really save myself any money in the long run. My advice, go to a store that specializes in running shoes to find the right fit.
