I admit I'm a gear junkie and have tried them out. I've put 450 miles on my first pair, yes I did buy a second pair. For me they've really helped me become a better runner (at least I believe so). It actually took me about 200 miles before I realized this and I actually had more pains in my legs when starting out with them. But I think this was because it changed my running style to be more forefoot, and I was using muscles which I was not accustomed to. When I fatigued I would go more heel. Now after long runs my legs feel much more fresh than they use to.<br><br>
I had some issues with my left heel that have completely gone away with Newtons. That may be coincidence, who knows, but I just finally got my second pair. At about 400 miles they felt different. It was difficult for me to buy a second pair at that cost, and I almost went back to my 60 dollar pair of mizunos. But now I run much less then I use to when I just did marathon training, so I get more time out of them. I definitely do not think they will make you faster or anything, but possibly more efficient, depends on your running style now. I'll keep at them at least for 2008.
