ASICS Gel Cumulus 21 Knit updates

Delivers security and wobble-prevention 

Fit-wise, the elements that work in tandem to deliver security and wobble-prevention are the stretchy and sock-like upper fabrics and the semi-curved shape of the platform. The natural curvature of the human foot is the basis of the overall design.

AHAR or ASICS High Abrasion Rubber is the material that is used for the external pad of the ASICS Gel Cumulus 21 Knit. 

Gel Cumulus 21 Knit provides reliable traction

This compound is tasked with protecting the base of the midsole and its contact points from the abrasive nature of the surfaces. It also delivers traction, a trait that is fundamental to the quality of the run and the safety of the runner.

Forefoot flex grooves provide the platform with the capacity to bend along with the foot as it gears itself for the toe-off. Energized liftoffs are what serves as the end-point of these elements.

Absorbs impact shock

FlyteFoam Lyte is used as the base midsole piece. The job of this layer is to absorb impact shock during the landing phase while also ensuring comfort throughout the running session.

The lightweight construction helps to prevent any feeling of being weighed down by the shoe.

Energizes the toe-offs 

A FlyteFoam Propel topsole is meant to offer a snappy performance and a refined forefoot lift. The somewhat stiff structure helps to energize the toe-offs while also encouraging a perception of balance whilst the foot is resting on top of the cushioning system.

GEL is a shock-absorbing technology that is placed in both the forefoot and heel. This silicon-based feature prevents discomfort by mitigating the landing shock, thus causing a smooth heel-to-toe transition. 

ASICS Gel Cumulus 21 Knit offers a seamless wrap

GEL is used in many ASICS running shoe series, including the venerated Gel Nimbus line. A knitted textile is used for the upper unit of the Gel Cumulus 21 Knit. The job of this element is to provide a form-fitting and seamless wrap.

ASICS Gel Cumulus 21 Knit breathable

It has breathing pores for ventilation throughout the run. Printed overlays cover the sides and the eyestays. These elements are thin yet able to help with the attainment of an agreeable foot-wrap.
