This year marks the 25th anniversary of the original ASICS Kayano and per usual, ASICS pulled out all the stops for their flagship maximum stability shoe. The Kayano will continue to be a go-to daily trainer for overpronators seeking plush, comfortable, and reliable protection.
With several updates from top to bottom, it seems like ASICS tried to address design flaws of previous models while staying true to the essence of the Kayano.
After receiving feedback that the original FlyteFoam midsole material featured on the previous version of the Kayano was too firm, ASICS went back to the drawing board. They ended up creating two new versions of FlyteFoam, both of which are showcased in the new ASICS Gel Kayano 25. Sitting directly on top of the outsole is the new FlyteFoam Lyte which uses wood pulp to reinforce cell walls rather than kevlar. ASICS claims this new material is more environmentally friendly, more durable, and even lighter than the original FlyteFoam. To give the Kayano more bounce and a softer step-in feel, ASICS added a layer of FlyteFoam Propel on top of the FlyteFoam Lyte. Additionally, you get ASICS’ trustworthy silicone gel in the heel and in the forefoot, however, the forefoot gel is now hidden within the midsole. The combination of these materials should offer a soft and bouncy ride while maintaining the shoe’s ability to stabilize the moderate to severe overpronator.
To further reduce overpronation and provide stability, the Kayano 25 uses a couple different technologies. The Dynamic Duomax Support sounds complex but is just a fancy way of saying that the shoe has a firmer material on the big toe side of the shoe. As the overpronator rolls from softer material on the pinkie toe side of the shoe towards the big toe side of the shoe, it runs into the firmer material which doesn’t compress as easily and therefore reduces the foot’s ability to roll inward. This firmer material is assisted by a trusstic system which limits the shoe’s ability to twist from side to side.
The outsole remained very similar to the previous model. However, while the last version had a triangular design, the Kayano 25 features a hexagonal design to increase flexibility. ASICS continued to use carbon rubber in the heel for exceptional durability and a blown rubber in the forefoot for responsive cushioning and flexibility. In comparison to the 24, the Kayano 25 is slightly more flexible in the forefoot which should make for a smoother ride.
Another feature to look forward to in the Kayano 25 is the addition of a jacquard mesh upper which debuted on the $250 ASICS Metarun back in early 2017. This mesh technology provides lightweight breathability that tightens and loosens in key areas to allow the foot to move naturally while still maintaining its structure. In addition, the Kayano has a similar heel clutching system as used on the MetaRun and Kayano 24, which locks the heel into place and provides additional stability upon impact.
Finally, after comparing the fit of the 25 to the 24 we found them to be very similar, with the 25 being slightly more accommodating due to the stretchier jacquard mesh.
