To some people, a sneaker is a sneaker. When you put in as much time at the gym and on the sidewalks as I do, a sneaker is so much more.
I am loving the new Axiom 2 shoe ($90.00) from Brooks Running because it is a lightweight yet ultra supportive trainer that works with people who may (or do) have pronation tendencies. Its Diagonal Rollbar -- a wedge-shaped piece of high density foam that is positioned on the medial (arch) side of the midsole to reduce the rate and speed of pronation -- makes the shoe flexible enough to allow for natural movement while still being supportive. More basically, these shoes are great for anyone training, whether it is on the treadmill or on the pavement. Get yourself a pair directly from BrooksRunning.com.
