If you're looking for a fantastic workout shoe, the Nike Metcon is officially my favorite (I have them in this pretty white/gold color combo). For years, I always gravitated toward a running shoe when needing a new pair of sneakers for the gym. However, I’ve been working with a prenatal trainer during my pregnancy who pointed out the importance of having a cross training shoe. Duh, Mary. If your workouts involve things other than running like weights, squats, lunges, burpees, TRX—anything of the Kayla Itsines variety—a cross-training shoe like these favorite Nike Metcons provide much better support and stability than a runner. Bonus points for being completely chic and kind of begging to be worn outside the gym, too.
