Weaknesses: Really soft - not for people with weak knees as these shoes do not feel stable due to the pillowy ride mentioned in the RW review. Its like running on marshmallow.
[Update 10/03/09] By far the worst grips on any running / training shoe i have had.
Overall: A nice shoe which is extremely cushioned. Unless you are looking for pure cushioning, there are much better shoes out there.
Strengths: Instant snug fit, great grips & very breathable and lightweight. An instantly comfortable shoe.
Overall: A fantastic shoe & a great update from the Triumph 5. In the previous model i could feel the midsection of the sole underneath my foot until the shoe wore in and became more comfortable over time. In this version the fit was instant and the ride extremely comfortable. Having worn 4 different shoes over the last year or so this is by far my favourite.
