Strengths: Light, hardwearing (I did serious miles before just buying my second pair), good arch support, Stylish!
Weaknesses: They don't give loads of protection against puddles but the only thing that really does is wellies and who wants to run in them?! Other thing is they stop half sizes at UK 12! I could go up half a size if they had them!
Overall: I'm now on my second pair of Mizuno Wave Nirvana's. The first was 6 series and these are 8's. They have worn really well and are very comfy! Loads of arch support. I think I'll be in Wave Nirvana's forever!!
