  • A comfortable fit is felt when runners wear the Adidas Climachill Cosmic Boost. This is a responsive Adidas running shoe handles traversal on the flat surfaces with ease. The appealing upper unit uses a material that resembles a woven cloth, giving constant ventilation for the foot. This shoe is truly a comfortable running partner that’s reliable and efficient.
  • The upper unit of this running shoe has been engineered to provide natural, breathable support for the runner. A sock-like fit is also afforded to those who wear this shoe, making sure that the material is able to allow natural movement and flexibility. The interior sleeve is even wrinkle-free, thus preventing skin irritation and blistering.
  • The mid-sole unit of the Adidas Climachill Cosmic Boost uses two separate cushioning systems to provide a responsive and easy ride to the wearer. At the front section is the proprietary technology that’s made from the compaction of TPU pellets that release energy to the foot. Running from the heel to the mid-foot is an EVA foam that absorbs shock.
  • Protection from wear and abrasion is part of the purpose of a reliable outsole unit. The Adidas Climachill Cosmic Boost uses Stretchweb, an elastic compound that works with the boost™ mid-sole to provide balance and efficacy in performance and surface control. Traction is also superb when it comes to this technology.

The Adidas Climachill Cosmic Boost has a regular shoe length. The sizes that are available for this model follow the measurements to which men and women are accustomed. The width of this shoe is medium, so it accommodates those with medium sized feet. Its semi-curved shape allows the natural shape of the foot to fit well into it.

Like the popular Adidas Pure Boost, the Climachill Cosmic Boost uses the Stretchweb Rubber Outsole which offers durable protection when it comes to the abrasive nature of the asphalt. It shields the sole unit from any potential damage caused by surface friction and other road debris. It’s also elastic, so it adapts to the runner’s performance in relation to the ground, while also giving reliable traction.

The boost™ technology is a unit that’s placed at the front of the Adidas Climachill Cosmic Boost. It’s made from durable TPU capsules that have been compacted together to create a responsive and comfortable underfoot experience. It transfers energy to the wearer, making sure that performance is always energized.

An EVA Platform gives the runner a smooth and controlled ride. Placed at the rear-to-midfoot section of this shoe, it gives responsible underfoot cushioning, as well as shock absorption. It doesn’t wear off easily, so it keeps the mid-sole effective, even after many uses.

The Primeknit technology is a soft material that resembles woven cloth. Engineered from the mid-foot to the front of the Adidas Climachill Cosmic Boost, it wraps the foot snugly and gives it breathable support for a dry and cool interior environment.

The AIRmesh is placed at the rear section. It holds the foot in and keeps it in place, making sure that accidental shoe removal is prevented. It’s highly breathable, so air is constantly encouraged to go in the shoe to ventilate the foot.

A removable insole adds a bit more cushioning and it accommodates medical orthotics.
