The GEL-CUMULUS® 25 neutral running shoe features some updated technologies to help improve the shoe's cushioning, comfort and underfoot feel. The new midsole design features a single layer of FF BLAST™ PLUS cushioning and a 2mm stack height increase, making this the most cushioned GEL-CUMULUS® model to-date. The rearfoot PureGEL™ technology is lighter and softer than previous versions of the material, allowing for a softer and smoother transition during your stride.
The GEL-CUMULUS® 25 running shoe is also more sustainable than previous models, with roughly 90% of the shoe's upper polyester being made out of recycled materials.
