Strengths: Excellent cushioning Look good (Mine are black and yellow) Excellent achilles heel protection
Weaknesses: Feel a bit clumpy on my quite narrow feet. Much better when pulled very tight but that does cause some distortion of the shoe near the toes. Seem to make my feet very hot, guess the ventilation is not great.
Overall: A decent trainer that I'm pretty pleased with as I got them for a good price online. If I'd paid full whack for them I would be a touch disappointed. I do like how they look and a lot of people comment on how much they like them, but I've bought a pair of Asics Gel Hyperspeed 4 for a lightweight alternative as the Nike's feel a little larger and heavier. No doubt the cushioning is excellent, but with my slight build I think I prefer something a little lighter.
