Off topic, but for the ladies on here to run, do you have a favorite pair of running shoes? Mine are getting worn out and I can't decide on a new pair!
Amanda - It really depends on your foot/gait/distances/etc... but I really do recommend going to a place that will do an analysis for you.
I thought I needed a support cushion shoe, like an Asics. Turns out I need a neutral shoe. With my foot, I love love love the Nike Pegasus. I still get shin splints, but they are tolerable now. Before they were debilitating!
Oh and they also made a custom insole for me. The Pegasus will only last 500 miles, but the insole with be good for 1000+ minimum, so I can reuse them with my next shoe.
