Technology that works as hard as you do

Infinergy® is an advanced cushioning system originally developed for high-performance running and now fully optimized for safety footwear.

At its core are thousands of E-TPU beads that compress under pressure and instantly rebound. Instead of absorbing energy and losing it, Infinergy® gives it back, step after step.

This continuous energy return helps reduce fatigue, especially for workers who spend long hours standing or walking on hard surfaces like concrete.

Compared to traditional midsoles, Infinergy® delivers significantly higher energy return, improving comfort, mobility, and overall performance throughout the day.

Direct injection is an advanced construction method used to permanently bond the sole to the upper without the use of glue or stitching.
The upper is precisely enclosed within the mold as molten, multi-density PU is injected around it, creating a seamless, one-piece construction.
No glue. No stitching. Just pure integration.
Combined with an Infinergy® core, this construction returns energy with every step, reducing fatigue.
Targeted cushioning and support are engineered directly into the sole, delivering lasting comfort, flexibility, and durability from day one.
Compared to traditional methods, direct injection delivers a more consistent structure, providing long-term performance and immediate comfort from the first wear.

Slip resistant outsoles are engineered to improve traction and stability in work environments where surfaces may be wet, oily, or uneven. Advanced outsole compounds combined with purpose-designed tread patterns increase surface contact and grip, helping reduce the risk of slipping during movement, directional changes, or sudden stops. By improving underfoot control and stability, this technology supports safer movement throughout the workday, providing more secure footing and greater confidence in demanding or fast-paced conditions.

Safety toe protection is designed to protect against impact and compression while maintaining comfort and reducing weight compared to traditional steel solutions.
U-Power offers multiple AirToe® technologies, each engineered to meet safety standards while improving fit and wearability across different work environments.
