Strengths: A comfortable, well fitting shoe. I run approx. 40 miles per week, on and off roads and have never had any blisters.
Weaknesses: They suit my running style, a slight pronator but would probably not suit a greater pronator. Also the cushioning is adequate for me, a light weight 10 stone but probably not enough for heavier runners.
Overall: A great shoe for training and racing all distances, including the marathon. I also have three pairs and am looking forward to the next upgrade.
