With a top-of-the-line FluidRide midsole, larger Rearfoot and Forefoot GEL Cushioning units, and updated Guidance Trusstic System, the sixteenth version of the GEL-Cumulus is the most cushioned and lightest version of the GEL Cumulus ever.

• Pronation suitability: Underpronator to neutral to mild overpronator; Heel height: 22 mm; Forefoot height: 12 mm; APMA Seal of Acceptance
• Rearfoot and Forefoot GEL Cushioning Systems: Larger units attenuate shock during impact and toe-off phases; allows movement on multiple planes as the foot transitions through the gait cycle
• FluidRide midsole: Provides the ultimate combination of bounce-back and cushioning properties with reduced weight and exceptional durability
• Updated Guidance Trusstic System: Provides a silky smooth transition to complement the plush FluidRide midsole—integrates Guidance Line construction for enhanced gait efficiency, while providing midfoot structural integrity
• Guidance Line: Vertical flex groove in outsole decouples the tooling along the line of progression for enhanced gait efficiency
• Impact Guidance System: Linked components enhance the foot’s natural gait from heel strike to toe-off
• AHAR (Asics High Abrasion Rubber) placed in critical areas of outsole for exceptional durability
• DuraSponge outsole: A blown AHAR rubber compound for enhanced cushioning and durability in the forefoot
• Open-mesh and synthetic upper for breathable comfort and support
• ComforDry sockliner provides cushioning performance and antimicrobial properties for a cooler, drier, healthier environment
• Independently placed eyelets disperse lace tension, creating a customized fit and enhanced upper comfort
• Gender-specific cushioning: Women’s models feature lower-density top layer in the midsole, allowing benefits of midsole compression
• Pronation is how a runner's foot rolls laterally between heel strike and toe-off: Underpronation is when the foot rolls outwards, overpronation is when it rolls inwards, and a neutral pattern is when little rolling occurs
