Everything’s better with Helion! On updates its stability classic to include their lighter, bouncier and more resilient Helion foam to enhance that ride you already know and love. Using a dynamic stability in using geometry as in previous versions, the Cloudflyer is the perfect option whether or not you overpronate or not. The top lace loop of the star pattern was moved out of the path of the main flex point of the shoe which should also help for durability and comfort. As if this shoe didn’t fly off the shelves before (no pun intended), good luck finding a pair in your size!
