'Having run in Kayanos for years I bought a pair for running on the Forest Tracks- one word: impressive'
Strengths: Reliable Asics fit, comfortable, plenty of grip for most conditions, support is consistent- the gel does its job.
Weaknesses: Skinny laces!
Overall: I have to say I am impressed with the extra grip these gave me off-road. I can really tell the difference when I get onto harder surfaces - a little more shock felt on my ancient calves but not too bad at all - on muddy tracks - superb. Obviously when the mud gets ankle deep they struggle, but don't we all?
