Strengths: Great comfort offering good cushioning and suppport. They also feel fairly resposive and have a great fit for a slimmer foot.
Weaknesses: Can't think of any.
Overall: I've chopped and changed with my shoes and have Nike air Triax, Pegasus, Asics, and others sitting in my cupboard not being used. I ran my first marathon in a pair of these and won't be using anything different for the foreseable future.
