Heat Always Rises. You bring the heat every mission, but when the mission brings the heat right back, the Scorch is here to serve. It's built first for breathability thanks to a lightweight upper patterned with mesh panels*. The Plylolite midsole and the speed lace system work together to make it light, agile and ready when you are, while the outsole is slip resistant and designed for stability. When the heat is on, the Scorch is extra breathable to keep you cool all the way down.*Mesh panels are transparent and may reveal sock color or pattern.
