Every session, no matter how big or small is worth it. The Nike Metcon 9 improves on the performance of the 8 with a larger Hyperlift plate and extended rubber rope wrap. Those improvements pair with the dual-density foam midsole and engineered mesh upper to deliver superior comfort and performance on the gym floor. The gold standard for training shoes, it's built for lunges, lifting, HIIT training sessions and everything else between.
