As a runner, I started to get shin splints while wearing a newly purchased pair of Asics gel Kayano 18 sneakers (even with orthodics!). I would switch to my old pair of Saucony Grid Cohesion 3's and voila, no shin pain! So I decided to try a pair of these Saucony Grid Cohesion 5's, and lo and behold, no shin pain!!! Tried my Asics again, and had shin pain. So I am now married to Saucony for life! :)  I just hope they don't change anything about their Grid Cohesion line. They are perfect! I tend to overpronate, and have a low to med arch, and I did place an orthodic in these, and it feels great. There is also more toe room than in Asics, so I did not need a wide width. But I would suggest going up 1/2 size in any running shoe. Just love these - I can run forever in them!
