I have purchased this brand of shoe several times and get a few hundred miles out of each pair. The only problems I have are when they get worn: holes come through the mesh of the toe and the side design cracks (this is after 400-500 miles). They have worked great for me so far and I will continue to get them.
Love, love, love these shoes. This running shoe is the most comfortable I've ever worn. The sale price was the selling point for me, I didn't really need any shoes right now but I couldn't turn down that price! I still have a pair from 3 years ago that I wore for running and they are still good enough to kick around in and they still look practically new! I would recommend these shoes to anyone!
