PROFILE
For all runners who look for a stable, very well cushioned, and extremely comfortable running shoe. The newly developed True Motion Transparent Hybrid Foam, made from EVA, TPU, and TPE, combines soft cushioning, high responsiveness, and long-lasting durability. The new insole made of open-cell memory foam provides additional comfort and a personalized fit. 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 4.
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.
