Whatever your "why" is for working out, the Metcon 9 makes it all worth it. We improved on the 8 with a larger Hyperlift plate and added rubber rope wrap. Sworn by some of the greatest athletes in the world, intended for lifters, cross trainers, go-getters and it's still the gold standard that delivers day after day. Tougher and Stronger We made the Hyperlift plate in the heel even bigger for stability when getting after tough workouts like split squats, dead lifts and other lower-body exercises. The plate helps force weight down and out while adding rigidity in the heel. That firmness helps you feel grounded and supported, specifically under heavier loads. Secure Feel The lace lock system attaches to the shoe tongue, so you don't have to worry about latching it to any fabric. It helps keep your laces in place, so once you tie up, you can focus solely on your workout.
