Strengths: A great shoe that for me is great straight ot of the box (10 miles). I was using the GTS 6 before and can feel no difference in fit between the 2 so all is well.
Weaknesses: Slightly on the narrow side (like the GTS 6) so i have to doctor the insole slightly, but once done it goes for miles and miles with no problems.
Overall: A great stability shoe with loads of shock absorption. Very light, very comfortable out of the box, and not over priced.
