On Running Cloudflyer 4 Running Shoes

On Running Cloudflyer 4 Running Shoes On Running's Cloudflyer 4 Running Shoes deliver plush cushioning and a stable ride. The dual-density CloudTec® sole is made up of Helion™ superfoam in the forefoot to soften landings and create explosive take-offs, while a denser material under the heel helps support the runner's natural gait. Working in harmony with the CloudTec cushioning is the Speedboard®, a liquid-injected plate of thermoplastic polymer that converts energy from the landing into forward propulsion, essentially providing free speed. Zero Gravity foam on the outsole enhances both traction and durability. A re-engineered mesh upper maximises breathability so the foot remains at a comfortable temperature even through hard efforts and the tongue is now plusher and more cushioned for enhanced comfort. The foot is kept secure in the shoe thanks to a moulded sock liner and external heel counter.
