The Cloudmonster 2 features our biggest CloudTec ever. Yes, you read that right. For massive cushioning, mega bounce and maximum energy. It's a monster ride on the road with an unmatched forward-rolling motion.An updated nylon-blend Speedboard is sandwiched between a dual-density Helion superfoam midsole, which makes for softer landings and better impact absorption. Increased energy return, forward momentum, and powerful take-offs make for an irresistible road run.We've ramped up the recycled content with mesh on the upper made from 100% recycled polyester. And by using more sustainable materials and processes, weve increased the overall recycled content to 24%.
