AHAR+ : Heel : A thinner and lighter version of Asics High Abrasion Resistance rubber. It is placed on the impact area of the outsole to reduce excessive wear.

Asymmetrical Lacing Design : This set-up inimprove the ASICS Biomorphic Fit by creating a more anatomically correct lacing pattern. The asymmetrical lacing design is configured to wrap across the top of the vamp, creating a more open forefoot environment.

DuraSponge® : A new blown rubber compound for enhanced durability and cushioning in the forefoot.

Gel® : Provides maximum rearfoot and forefoot shock attenuation.

Solyte™ : The advantage to injected Solyte® is a much more consistent density, ensuring that the desired softness is more ‘dialed in’ than standard compression molded midsole material. Injected Solyte® is also lighter than standard Solyte® contributing to the overall drop in weight.

Racing Trusstic System™: : A lighter weight trusstic system designed for faster turnover : Trusstic System™ : Moulded component under the midfoot area. Provides over-pronation control in combination with extremely contoured midsoles. Reduces the weight of the shoe.
