Named for a woman’s double X chromosome DNA sequence, the Puma Run XX Nitro Nova Shine gives you Puma’s everyday cushioning and stability in a female-specific design. The Run XX Nitro’s updated fit is made to hug a woman’s foot at the heel, instep and arch so you’ll feel comfortable and supported all day long. This Nova Shine edition of the Run XX Nitro also features an upper with reflective design elements to help you shine bright when you’re running in low-light conditions. Striking the perfect balance between durable and lightweight, a responsive NITRO midsole foam keeps you feeling bouncy on your feet. When your run goes long and your legs start to feel tired, a firmer rim of RUNGUIDE foam helps promote proper alignment and keeps the foot centered through your stride. From the road to the sidewalk to the track, a durable PUMAGRIP rubber outsole gives you multi-surface traction. With a breathable mesh upper, female-specific support and energetic cushioning, run confidently in the women’s Puma Run XX Nitro.
