Strengths: Light, fast, incredibly comfy from mile one and great in the wet.
Weaknesses: Not enough shops stock them.
Overall: I've tried a lot of running shoes and nothing else comes close. These are so light, so comfy and so damn fast it's scary. Amazed at the comments about lack of traction in the wet, they better than anything I've had before and one of the things that impressed me. I've used these for 2 half marathons, a 16 mile trail run and several shorter speed sessions - they just do everything superbly.
I've done nearly 100 miles in mine and they look like new - not sure what the poor durability comments are about, these will go over 400 miles easy.
