Runner Profile
For all runners who look for a stable, very well-cushioned, and extremely comfortable running shoe. We don't use categories like neutral or support. Our technology centers the point of force application during your gait cycle. Thus, we remove the cause for non-physiological stress and avoid the occurrence of problems in the first place. No matter whether you ran in a neutral or a stability shoe or used orthotics before, you are secure and well-protected in the U-TECH Aion 3. In comparison to the U-TECH Nevos 3, the U-TECH Aion 3 provides more cushioning and increased comfort. Even compared to the U-TECH Aion next gen, the U-TECH Aion 3 offers 40% more foam. The asymmetrical design of the U-TECH™ tubes (Biological U-TECH™) is based on the anatomical-biological structures of the foot and enables extremely soft running and perfect centering of the forces.
In addition, the U-TECH Aion 3 is the most sustainable True Motion running shoe to date thanks to even more fully recycled materials.
Offset
Statically 10 mm. Since your foot sinks into the center of our Biological U-TECH™ Technology when you run, it is at a dynamic foot-neutral offset of 0 mm in less than 50 ms after footstrike. This enables a highly efficient stride, reduced load, and a maximum responsive push-off from the ground.
Use
Short, long and ultra-long runs on predominantly firm surfaces.
