Recovering energy while working...


It would be great but it seems impossible: when you work, your energy is used up, not recovered!


Yet, this is not the case.Today, research has found the answer that can help us, and recovering energy while working has become a possibility.
This technology is called Infinergy® and it is a real breakthrough in innovation.
In fact, Infinergy® can return more than 55 percent of energy with each step, resulting in shoes that return energy!





Infinergy® is the first expanded TPU that combines lightness and elasticity in a single product.
This material was developed by BASF Group, a world leader in the chemical industry, which designed it to meet the needs of the world of sports and, in particular, the world of running.


We are talking about an innovative mixture of foams, consisting of closed-cell particles combined with those of thermoplastic polyurethanes capable of recovering energy.





Infinergy® isa material capable of transforming traditional cushioning into dynamic cushioning that can alleviate the strain your feet and legs are subjected to while running, but when applied to a safety shoe, it can relieve fatigue and restore energy.


Let's find out about Infinergy® in more detail!








Infinergy® provides real effectiveness that helps save energy much longer than a traditional sole with a guaranteed effect of lightness, freedom of movement, reduction of musculoskeletal disorders and relief of the sense of fatigue, thanks to its many benefits:



  • Flexibility and lightness;


  • High tensile strength;


  • High resilience;


  • Resistance to thermal temperature changes (-20° to +40°);


  • Abrasion resistance;


  • Low density;


  • Superior rebound coefficient of 55%.




What it means.


It means that in the phase of adhering to the ground, your energy is conserved and then returned in the phase of moving your foot by pushing it forward: over 55% energy returned with each step!


Optimal cushioning, excellent and long-lasting resilience despite constant stress and despite temperature changes.





From the collaboration with BASF, comes RED LION, the range/assortment of work shoes that combines the natural flexibility of the Infinergy® insert-light, flexible and perfectly adhering to the ground surface-with the recognized quality of the U-POWER brand.
