Convergence gel® technology provides two points of engineered support by replicating the fatty tissue of your foot. Combine that with the new engineered mesh upper for increased breathability and support, the gt-1000™ 5 shoe has the performance and stability of its predecessor with the latest in stability technology, and did we mention it’s 0.5 ounces lighter this yearImpact Guidance System (I.G.S) (Running) : ASICS design philosophy that employs linked componentry to enhance the foot’s natural gait from heel strike to toe-off.
Rearfoot and Forefoot GEL Cushioning Systems: Attenuates shock during impact and toe-off phases, and 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 decouples the tooling along the line of progression for enhanced gait efficiency.
Guidance Line Midsole Technology: Vertical flex groove decouples the tooling along the line of progression for enhanced gait efficiency.
The black specks on the medial side of the midsole are intentional and identifies a section of the shoe in which a technological feature exists. These black marks are not a defect.
