I've been considering Newtons for over a year now, since the Ironman Wisconsin expo in 2008. At the time I was gearing up for a marathon and was afraid to make a switch so my plan was to wait until winter. But then I started training for the Ironman and again, was afraid to make a switch. Now that I've had a 3.5 month running hiatus due to the worst injury I've had yet, I feel like it might finally be a good time to consider a transition. I've read countless articles, blog posts and message board debates and in the end, like what I've learned. Slowtwitch recently posted this review that gave me the final push.
I am planning to go to a Newton dealer this weekend to figure out which shoe is right for me. They have some intermediate transition shoes for people like me who are used to overly cushioned stability shoes so that might be a good way to go. Either way I'm thinking I'll do just one run a week in them until I feel adjusted, and hopefully can ease into full time by summer. I'll let you know what I end up going with.
