Glycerin Flex

Daily Trainer2026-02-20 · JP · Release dateChecked 2026-10-23

Glycerin Flex is a road trainer for daily miles and long runs, with an emphasis on moving with the foot. FlexZone pairs an asymmetrical midfoot flex groove with a podular lateral forefoot for flexibility from landing to toe-off. Dual-cell DNA TUNED tunes cushioning between heel and forefoot, while a breathable flat-knit upper stays flexible around the foot.
