Strengths: Very comfortable and supportive but also feel light compared to my previous Saucony's so I feel less of a plodder and more of a runner!
Weaknesses: They are in the higher price bracket but you definitely get the quality at that price.
Overall: Fantastic shoe, no obvious weaknesses. My current mileage is 60-70 miles a week and these shoes are coping brilliantly. Really comfortable and help with my over-pronation. They also come in two colours, blue and orange, handy if you want to alternate two pairs.
