Best for
The Glycerin Flex takes the plush Glycerin idea and adds FlexZone, a midfoot section meant to let your foot follow its own motion path. The cushioning is soft and designed to move with you rather than hold you still, on a 6 mm drop and at about 258 g.
It suits easy and long road miles, especially if a stiff platform starts to fight you by the second hour. Recovery days and steady long runs are where a bending midfoot earns its keep.
It is not a fast shoe. Nothing here points to a springy racing foam or a plate, so tempo work feels heavy, and a flexible midfoot offers no stability correction if you happen to need one.
