The U-TECH Aion is your ideal companion for short to long and ultra-long runs on predominantly firm surfaces. The full-length U-TECH™ technology ensures maximum comfort, which catches you softly even after dozens of kilometers due to our U-TECH™ Foam. Or simply put: a new dimension in comfort. How far will your next run be?

We love the feeling of freedom that running gives us. Just like you. When we run, we want to forget our everyday life, discover unknown places or reach new goals. Nothing is more frustrating than having to take a break because of injuries. We understand this all too well – and that's why we developed U-TECH™.

A study with more than 1,700 participants shows that runners who run with U-TECH™ have a 21% lower risk of injury. The risk of knee injuries like runner's knee is even reduced by more than half with U-TECH™.*

Whether you're an overpronator, supinator, or neutral runner, whether ou're just getting started or have already accumulated thousands of running miles, the horseshoe-shaped midsole wraps around your foot like a pocket of fat – to make your run more efficient, more comfortable, and more stable. Or in short: what are you waiting for? Take the freedom to run whenever, wherever and however you want.
