Loved the shoe.  I had no issues during longer runs and they are very comfortable.  I am a fore foot strike runner and I prefer a low heel drop ( 0 - 4 mm).  These shoes felt great on various terrain -- concrete, asphalt, dirt, gravel.  No issues with traction.

I do need to note that before reaching 100 miles on the shoes, the mini-pads on the soles started to coming off.  I personally think they are pointless and a weak point in the design, but I'm sure Saucony isn't the only one who does this.  Nevertheless, I contacted Saucony and they replaced them with the Kinvara 8.  Again, mini-pads on the bottom.  I'm hoping these fair better than on the 7s.

Overall, a good shoe and one I would put on my GoTo list even with the mini-pad issue.
