Key Features & Benefits

Unrestricted 58mm Stack: Exceeds the 40mm legal race cap to deliver unmatched underfoot protection and kinetic bouncy return.
Dual PWRPLATE Carbon System: Twin carbon-fiber plates sandwich the nitrogen foam to create an aggressive springboard toe-off.
NITROFOAM Elite Resilience: Premium nitrogen-infused foam maintains its explosive bounce over long-distance tempo runs.
High-Traction PUMAGRIP: Specialized rubber formulation ensures sticky traction on dry pavement, synthetic tracks, and wet roads.

Sizing & Fit Advice

Fits True to Size (TTS) with an aggressive race fit. Runners with wider forefeet (2E) should consider going half a size up due to the sock-like entry and narrow performance shape.

How to Find Your Size (Step-by-Step Guide)

1. Setup: Place a plain sheet of paper on a hard floor, flushed against a flat wall. 2. Position: Stand on the paper with your heel resting gently against the wall (wearing your preferred athletic socks). 3. Mark: Mark the furthest point of your longest toe on the paper with a pencil. 4. Measure: Measure the distance from the edge of the paper (wall) to your mark in Centimeters (CM).
Recommended Fitting Margin:
Casual / Lifestyle Sneakers (e.g., Suede, RS-X, Palermo): Add +0.5 cm to your measured foot length.
Performance Running / Athletics (e.g., Deviate Nitro, Velocity Nitro): Add +0.5 cm to +1.0 cm for comfortable movement and toe clearance.

Puma Signature Fit & Characteristics

Fit Profile: Puma footwear generally features a streamlined, athletic fit. Classic lifestyle silhouettes (like the Puma Suede) run true to size with a narrower profile, whereas modern NITRO™ running lines feature a broader, highly cushioned fit.
NITRO™ Foam Cushioning: Puma’s performance models utilize NITRO™ foam, providing responsive cushioning that molds comfortably around the foot over time.
