Strengths: Good overall performance. Relatively firm for a cushioned shoe. Decent comfort and support.
Weaknesses: Slightly too wide in the forefoot. Upper isn't the most hard-wearing, particularly if you run off-road.
Overall: Overall, yes, it's good, but not really a very exciting shoe. Functionally effective, no doubt, but lacking that X-factor. Pleased to move on to Nike's LunarLite, which is lighter (albeit softer) and feels much more foot-hugging.
Strengths: Brilliant comfort - the fit of this shoe, the way it wraps snugly around the foot, is the best I have experienced. The feel quite racy even though they are well-cushioned. Hence, I keep these clean for track sessions and road races.
Weaknesses: None that I have experienced.
Overall: The most impressive pair of running shoes I have owned, the Adistar is supremely comfortable yet aggressive.
Strengths: I'm on my second pair of Vomero 2s, and have used them for everything - training and racing. They offer a massive amount of impact-absorption from their soft soles. The fit is perfect, as is the comfort.
[Update 27/03/08] Great comfort and superb cushioning; kept me injury- and blister-free for well over a year of training and racing.
Weaknesses: The compound of the soles is very soft and they do become misshapen quite quickly, although I don't think this means they're worn out. The tread also wears down fairly quickly.
[Update 27/03/08] Both pairs of Vomero 2s I owned were completely destroyed by the time I replaced them. Each pair lasted about six months (25ish miles per week), which I guess is OK. What was worrying was how quickly the ultra-soft soles became deformed. I also think the soles were quite susceptible to cuts and damage when used off-road on rocky ground.
Overall: A top-rate shoe that has served me well for nearly two full seasons. Will I buy another pair next year? Quite possibly, although I may go for something slightly less squidgy.
[Update 27/03/08] I'm now wearing Saucony Triumph 4s for general training - which seem more hard-wearing, yet almost as comfortable. Do I feel tempted to go back to Vomeros? Not really, but they did serve me very well.
