Strengths: room for toes and crease when running does not bruise toes. Look good and very comfortable as i am big bloke
Weaknesses: the sole tends to feel a bit slippery
Overall: having used lots of shoes as a large bloke these have been the best by far. I am currently training for FLM 2007 and had no issues as milage creeps up to 17-18 miles on long runs
