The Pwr Nitro Squared is back for another season of Train Puma. This shoe offers a dual density Nitro foam outsole with a midsole banking to support you during lateral movements. You'll get rebounding and cushioning as you work out, so your feet - and your core - can feel comfortable, stable and supported during high-intensity training. Plus, when you're out and about, this model is a total eye-catcher. Lemlem x Pwr Nitro SQD Training Shoes
