True Motion - U-TECH Aion 4 - Springskor

Guided rolling with a biomechanical focus

The U-TECH Aion 4 from True Motion are entirely designed to support your natural running movement, instead of forcing it. Their centrepiece is the advanced U-TECH technology, which ensures your foot lands centred in the shoe and rolls in a controlled manner along the strongest path of movement. The goal is clear: to reduce your running stress without artificially changing your running style. In practice, the rolling of your feet feels calm, stable and surprisingly intuitive - especially over longer distances or when your muscles are tired.

Cushioning without sponginess

In addition, the newly developed midsole made from True Motion Transparent Hybrid Foam combines EVA, TPU and TPE. The result is a noticeably balanced blend of cushioning, stability and sensitivity. This means that the shoes are springy, without being too soft, and remain controllable even at higher speeds. Rocker geometry with a biomechanically calculated apex supports this feeling of control, which makes each transition from landing to push-off as smooth as can be. For you, this means less energy loss and a steady running rhythm.

Comfort and quality for everyday runs

True Motion uses recycled materials in the upper without compromising on comfort. Its breathable mesh fabric fits comfortably, while 3D print elements provide targeted stabilisation where guidance is needed most. In addition, the insole made from open-cell memory foam also contributes to your levels of comfort, especially during longer training runs.

Key benefits:

• Naturally guided rolling thanks to centred U-TECH construction
• Balanced cushioning with a stable and dynamic sole unit
• High level of long-distance comfort thanks to memory insole and fit
• Breathable upper with high recycled content
