Quick Definition: Supercritical foam is advanced midsole foam expanded using high-pressure nitrogen or CO2 gas, creating a lighter, far more resilient cushioning compound than standard EVA.
Why Supercritical Foams Excel
Traditional foaming relies on chemical blowing agents that leave irregular cell structures. Supercritical gas injection creates uniform micro-bubbles, maximizing energy return while trimming overall shoe weight.
Key Benefits
- Maximum Energy Return: Delivers spring-like rebound on every toe-off.
- Featherweight Cushioning: Significantly reduces shoe weight without sacrificing foam depth.
Top Recommended Shoes
- Puma Velocity Nitro 3 – Nitrogen-infused daily trainer offering explosive bounce.
- Brooks Hyperion Max – Uses DNA FLASH nitrogen-injected foam for fast workouts.
Frequently Asked Questions
Does supercritical foam pack out faster than EVA?
No, supercritical foams generally retain their resilience and shock absorption longer than traditional EVA foams.
