I am a big fan of Saucony shoes...this pair included. I really like the Grid Cohesion series but the style changed between Cohesion 4 and 5 and I wasn't impressed, so I went with this style instead. I will tell you that I am NOT a runner. I do not even jog. But I do participate in other types of aerobic exercise and I am on my feet constantly at work so I do need comfortable shoes for my feet. These shoes are very attractive in the grey/black/yellow color and just overall stylish. Although I've always worn a 6.5 in this brand of shoe, these are more narrow than others I've had in the past. It is still a very comfortable fit, just different than what I was used to. The bottom of the sole makes the shoes almost like mini cleats! Very good traction. The reason I gave 4 stars is due to the fact that these are thinner soled shoes than what I would have thought for a running shoe. I can feel larger stones/objects when I step on them in these shoes. So unless it's a fairly spotless trail to run on... .
