Strengths: They are light and very cushioned, keep my feet in-line and stopped all my achilles niggles.
Weaknesses: No good for xc!
Overall: Excellent - managed to get them cheaper than RRP and they've been worth every penny. Definately have them again (and I've tried quite a few models).
Weaknesses: Seemed to squash my feet and felt too undercushioned.
Overall: Never was happy with these. Had them recommended as well after gait analysis. However, always seemed difficult to lace them up in a way that made them comfortable. And I've had lots of niggles since wearing them.
Strengths: Very supportive (well, suppressive really) and comfortable to wear. I have the full-length version which is brilliant in winter for keeping your midriff warm.
Weaknesses: Takes some getting into, very difficult to get on without getting tangled up!
