It isn't a stability shoe or a cushioning shoe- it's a maximum support shoe, nothing less or more, and a great one at that. If it wasn't for the FlyteFoam midsole paired with Dynamic DuoMax Support System, nobody would confuse it as otherwise. By integrating the best of what running technology has to offer- an inevitable move considering its purposes and reputation- the Kayano 23 demonstrates that the best of both supporting worlds is possible even as those ideas change. That's because their intentions almost certainly embody the idea of running that captivates so many enthusiasts. Which can leave one to wonder just how much resilient comfort the shoes can provide? Quite a lot.
Midsole
Rearfoot Gel cushioning system uses a silicone-based gel for responsive shock absorption on impact.
Forefoot Gel cushioning system uses a silicone-based gel for responsive shock absorption on impact.
Convergence Gel helps dissipate shock better and increase overall effectiveness of cushioning.
FlyteFoam utilizes organic fibers that are embedded into the foam to offer lightweight resiliency.
Discrete Heel unit is a component of IGS that provides excellent shock absorption in the heel.
FluidRide provides responsive cushioning with reduced weight and increased durability.
Guidance Line is a vertical flex groove in the forefoot for improved gait efficiency.
Dynamic DuoMax Support System reduces over pronation by controlling the movement of the foot, leading to a smoother heel to toe transition.
Guidance Trusstic System is a lightweight support system that provides additional torsional rigidity.
Impact Guidance System (IGS) design creates a smooth and balanced heel-to-toe transition.
Gender Specific Forefoot cushioning uses an injected top layer of Solyte cushioning for additional comfort.
Upper
FluidFit consists of multi-directional stretch mesh that provides a personalized, glove-like fit.
Engineered mesh comprises the upper, providing lightweight breathability.

ComforDry X-40 Sockliner is made with anti-bacterial material to reduce odor and moisture and provide additional cushioning.
Strobel Last with the upper stitched to full-length ComforDry, for enhanced cushioning and a moderately soft underfoot feel.
Outsole
ASICS High Abrasion Rubber (AHAR) in the heel is made of carbon rubber for exceptional durability.
DuraSponge Outsole in the forefoot is made from a blown AHAR compound, for responsive cushioning and flexibility.
Rear Foot Crash Pad slows the rate of pronation, providing a smoother transition from heel-to-toe.
