Sole Technology

  • Outsole Technology

The outsole of Asics Gel Kayano 25 is not the standard AHAR rubber which is the staple technology of Asics. It brings in use the updated version of AHAR, i.e., AHAR PLUS which is better than its predecessor. It is better at absorbing the shock and sudden impact and adds toughness and durability to the running shoes. It has a consistency just like a sponge making it more flexible and lighter in weight.

Some specific areas of the shoes are covered with DuraSponge blown rubber which is softer than AHAR carbon rubber. It offers great cushioning and protection under the midsole.

The heel area of these stability shoes features crash pad which helps in controlling pronation and ensures a natural transition.

  • Midsole Technology

The midsole of these shoes features Gel technology which lends supreme shock-absorbing capacity to the shoes. This technology is used typically in the rearfoot and forefoot areas. The gel material which is silicone-based absorbs the impact and evenly distributes it across the feet. This offers a very responsive cushioning and enhances the gait cycle.

The IGS or Impact Guidance System which uses a Guidance line (a vertical flex groove) that guides the feet and minimize imbalance offers an effortless turnover. Furthermore, the Trusstic System supports the Guidance Line to offer additional stability.

The Dynamic DuoMax system is basically a wedge unit which helps in reducing overpronation. It incorporates dual-density midsole to regulate stability.

The midsole of these running shoes is dominated by FluidRide foam which is a perfect concoction of durability and lightness of SpEVA and responsiveness of SoLyte. Together they amplify the rebound efficiency, as well as toe-off cycle. This feature brings down strain from the muscles.

Another mention-worthy feature of the midsole of Asics Gel Kayano 25 is the use of FlyteFoam technology. The shoes bring in use two variants of this technology named FlyteFoam Lyte and FlyteFoam Propel. The former one covers the rearfoot area whereas the latter one covers the forefoot area.

The use of FlyteFoam Lyte helps in bringing down the landing impact, and the use of Propel offers a springy toe-off.

The OrthoLite X-40 brings amazing bounciness to the insole.

The mesh upper covers the internal underlays that provide support without hindering the flexibility. It also enhances the fit.

The Meta Clutch technology used at the heel area makes sure that you get a superlative heel fit. The additional use of PHF, i.e. the Personal Heel Fit, a double-layered memory foam lining offers optimum cushioning at the collar.
