The ISPA Flow 2020 SE focuses on the basis of the super-lightweight and breathable ISPA Flow by significantly supplementing the upper with new materials, lace toggles, a protective bootie, and a wider lacing system for lock-down. Somehow reminiscent of ACRONYM’s Air Presto transformation, this ISPA Flow 2020 SE is clearly meant for more inclement conditions as it swaps the thin mesh layers for a beefier, textured mesh. The circular vents at mid-foot and heel appear to be covered as well.
