Strengths: I'm a big guy, 17.5 stone, and do need something that takes a pounding. I've been in Nike, Mizumo's, Asics, Brooks and AT LAST I've found them. These NB's are fantastic. Comfortable for my 10ks, correcting my over pronation and still responsive and light enough. Size 12 wider width fits like a glove.
Weaknesses: Are there any? I ran in them for the first time then went straight out and bought another pair.
Overall: Believe me, I dont write reviews for a living - I'd rather be out running. I've been running regularly for over a year, 3-4 times a week, from couch to 5k and now up to 10k 3 times a week. I needed good shoes. I looked everywhere and - really - money was not an issue. These New Balance shoes are the best. I love them.
