Strengths: If they fit your feet they are probably good.
Weaknesses: I've just completed a long distance walk in them and my feet are so badly blistered that I have had to take time off work, and yes I have tried compeed, vaseline, doubleskin socks, white spirit etc. I've never had this problem with any other shoes so i can only assume it is my feet and asics not getting along together. I don't know if it's the new insole material but my feet just got hotter and hotter until the skin started to come off.
Overall: I appreciate that my review is very biased but I can only speak from experience. I will never wear asics again.
