Flexion

The Flexion uses U-Power's AirToe® Aluminum safety toe cap, rated I/C (impact and compression) under ASTM F2413-24. It is a lightweight metal-alloy toe that helps keep the footwear streamlined and less bulky than a traditional steel-toe design. Because it is metal, it will trigger a metal detector — if you need a fully metal-free option, look for our MF models instead.

Yes — the Flexion is best suited for Maintenance, Warehouse and Manufacturing environments, based on its I/C SD35 SRO safety rating, slip-resistant sole and overall construction.

Yes. The Flexion is rated SD35 (Static Dissipative), helping channel static build-up safely to ground. That makes it a strong option for electronics assembly, cleanrooms and other workplaces where uncontrolled electrostatic discharge can be a concern.

The Flexion has a Suede leather with breathable textile panels upper, combining breathable textile zones with durable reinforcement for better airflow during long shifts. Clean it gently with a soft brush or damp cloth, avoid soaking or aggressive scrubbing, and let it air dry naturally at room temperature.

Yes. Infinergy® in the Flexion is made from expanded TPU beads rather than conventional molded foam, returning 55%+ of impact energy with each step and helping reduce fatigue over long shifts. It feels springier underfoot and maintains its cushioning performance longer than standard EVA/PU foams, which can compress and stiffen over time.

The Flexion is a low-cut style on U-Power's Universal Fit last — a roomier toe box with secure heel hold. It runs true to size for most wearers; use our True Fit tool if you're between sizes.
