I'm of the theory that wearing differnt brands of shoes can help prevent injury since they all tend to be built slightly different. I generally have the Asics Nimbus, brooks defyance, and addidas supernova in my rotation. i also have some lightweight trainers.
the $100+ tag on the Nimbus has turned me off and i'm due for another pair.
anyone know of another shoe that is like the nimbus from either reebok, socony, or NB? i've tried some mizuno trainers but something just doesn't work in the forefoot for me.
