Designed fall 2021/spring 2022.

"Enjoy a stylish winterized version of the Fresh Foam X More v4 with the Permafrost edition. The most Fresh Foam used in any shoe to date, the latest in the line utilizes more Fresh Foam X, stacks it higher than ever before, and distributes it across the length of the shoe, offering a plush, yet stable underfoot experience. A data driven outsole applies the strategic placement of dramatic cushion zones and drastic flex zones promoting a natural stride while the silhouette’s rocker profile promotes a smooth transition and ride. All of this sits beneath a durable ripstop upper that keeps you locked with water-resistant comfort and support.”
