Strengths: Very stable..no blistering and good cushioning. Nice colours. Very quick to break into.
Weaknesses: Can be a bit stiff to begin with. Can't feel the cushioning system to begin with but it does work!
Overall: I was a 2120 user and after 200 miles, started having shin splints. After having my gait analysis again, was told to have a more stable shoe. First impression was that the shoes were stiff and slightly agravated my shin. My 2nd run was a half marathon and I was surprise no shin pains. Great stability and enjoyed the ride. The other thing is that I did not ache anymore in the evening when normally I have to do my stretching routine. Not cheap but I felt protected.
