The GEL-CUMULUS™ 25 running shoe is a great choice if you want a shoe with extra cushioning. Our lightest and most cushioned GEL-CUMULUS™ shoe yet, its comfort will put your mind at ease during your run. The shoe's PureGEL™ technology improves softness and shock absorption to reduce the impact on your joints. And we've increased the amount of FF BLAST™ PLUS foam. This is made possible thanks to the updated midsole design, which allows more foam to be placed for added comfort.
