Upgrading to Helion Super foam through the midsole, the On Women's Cloudrunner 2 Wide provides a softer feel and higher energy return than its predecessor. Combined with CloudTech cushioning, the deep stack of Helion provides a luxurious and energised feel that is super lightweight for a structured shoe. In the upper a durable heel clip and added reinforcements help to lock in stability and support to give you the most efficient stride. The tongue gets an upgrade, with a plusher finish you get an easier, more comfortable feel as soon as you lace up. The outsole has also been upgraded, offering the same durability and traction as before, but now designed to ensure it doesn't pick up stones as you go.
