Gender-specific engineering enhances the biometric performance of a running shoe set on the GEL-Cumulus's iconic fusion of cloud-soft cushioning technologies. Integrated compression pillars tuned to a man's specific gait create a smoother ride from heel strike to toe-off mile after mile. Cushioning: absorbs impact and distributes weight for consistent, buoyant comfort under each step Neutral: provides soft, even cushioning with an emphasis on comfort in any activity Lace-up style Removable, cushioned insole allows for custom orthotics GEL® cushioning in the sole absorbs impact and creates a smooth heel-to-toe transition FlyteFoam® midsole bounces back reliably with every stride, even on long-distance runs 3D Space Construction™ biometric engineering accommodates gender-specific compression on each heel strike ASICS High Abrasion Rubber (AHAR) withstands wear in critical areas of the tread Leather and synthetic upper or synthetic upper/synthetic lining/rubber sole Imported Men's Shoes
