The GEL-Flux will have underpronators to mild overpronators floating on clouds with shock-absorbing GEL cushioning and the bouncy SpEVA midsole. Guidance Line and Guidance Trusstic keep the ride smooth and efficient.
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: Attenuates shock during impact and toe-off phases; allows movement on multiple planes as the foot transitions through the gait cycle
SpEVA midsole material improves bounce-back characteristics and decreases midsole breakdown
Guidance Line: Vertical flex groove in outsole decouples the tooling along the line of progression for enhanced gait efficiency and a smooth ride
Guidance Trusstic System: Integrates Guidance Line construction for enhanced gait efficiency, while providing midfoot structural integrity
DuraSponge rubber outsole: AHAR (Asics High Abrasion Rubber) blown rubber compound for enhanced cushioning and durability in the forefoot
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
