I got 400+ miles out of these before retiring them.
I was pretty pleased with the shoes. They are a bit stiff - I've since moved to a more neutral shoe from Saucony. But, they held-up very well and gave me almost no problems.
I'm 220lbs with low arches and a bit of a supinator. The Guide is one of the best shoes I've tried (had the 7, a couple of the 8s and this pair). There is a bit more stability than what I would like, but think anyone looking for mild support would really enjoy this shoe.
