Practical experience with the Asics GEL-Kayano 18:
Bought, dressed, went 10-km test - all the best. Perfect damping is present on all surfaces (road, forest road, gravel). Interestingly, the slightly asymmetrical lacing through which the laces no longer be directly over the foot. At the beginning you should something lace loose here, because there is a different pressure distribution. The attenuation was wedge-shaped increased from front to back to 3 mm, which leads uphill to a slightly lower load on the Achilles tendon and downhill provides additional cushioning.
In my view, the shoe compared to GT, Gel-Cumulus and Gel-Nimbus series is the most cushioned running shoe and also the most thoughtful shoe. The most expensive way also. ;)
