Nike, I'm sorry, but I think we may be breaking up. A brand loyalist for years, these New Balance 813 Training Shoes ($80) are making me rethink my shoe choice these days. Stylish and comfy, I love how light and flexible these feel on my feet — almost like I'm wearing nothing at all. Supersoft with the right amount of support, these are my new mainstays for cardio classes and strength-training workouts.
