Miles feel effortless in the HOKA Skyward X. This supremely cushioned trainer takes soft and smooth to the extreme. It features HOKA's groundbreaking suspension system with a convex carbon fiber plate that compresses and springs back with every stride. A highly resilient PEBA foam sits closest to your foot for lively, cloud-like cushioning, while a super critical EVA frame provides a stable base below. In our full review of the HOKA Skyward X, run tester Mandy said, “I felt as if I was rolling through my runs and could run forever. This included both weekend long runs and shorter after-work runs. I liked running hillier sections in these shoes more than flatter sections because the combination of the carbon plate, cushioning and rocker shape allowed me to really let ‘er rip when going downhill.” Details: Upper: A flat knit upper with zonal engineering molds to your foot for a sock-like fit. Perforated material increases breathability while plush padding on the tongue and heel collar gives you a premium feel. A tapered heel collar reduces chafing and irritation on your Achilles, and extra eyelets allow you to tie the marathon loop to lock down the fit. Midsole: The Skyward X's midsole has three layers that work together to provide a comfortable and efficient ride. The first layer, closest to your foot, is made of PEBA foam, which gives a bit of cushioned bounce with each step. Beneath that is a curved carbon-fiber plate that compresses when your foot strikes the ground, storing energy to spring back and propel you forward as you push off. Finally, the bottom layer is an EVA foam that works with HOKA's signature rocker shape to create a smooth and effortless transition from heel to toe as you walk or run.
