Dual-density stack: FF Blast Max over FF Blast+; FluidSupport medial wedge
The Gel-Kayano is the most famous stability shoe in running, a three-decade franchise built on firm medial support and premium cushioning. The Kayano 30 threw that recipe out in 2023: the medial post gave way to a soft, wide 4D Guidance System platform. Reviewers loved it. A visible chunk of the old guard did not, and this page tracks both eras, what changed in each version, and where the old formula can still be bought.
