ASICS® Gel - Noosa Tri 7 - Men'sThe eye-catching ASICS® GEL-Noosa Tri™ 7 running shoe combines triathlon specific elements with go-fast GEL-DS Trainer tooling for optimal performance on race day. Open mesh upper enhances ventilation and a perfed sockliner helps drain perspiration. Soft materials and limited interior stitching in the upper construction allow the shoe to be worn barefoot. Impact Guidance System (I.G.S.®) employs linked componentry that enhances the foot's natural gait from heel strike to toe-off. Guidance Line is a vertical flex groove component of I.G.S.® and is primarily articulated in the forefoot to improve gait efficiency. Forefoot and heel GEL® Cushioning Systems attenuate shock during impact. DuoMax® Support System is located in the medial midfoot and is designed to reduce excess pronation. Propulsion Trusstic System® mimics connective tissue in the foot by creating tension as foot enters propulsion stage. Space Trusstic System® creates a pocket between the Trusstic System® device and the midsole, allowing for controlled midsole deformation and more efficient foot function. Dual-density Solyte® midsole employs different densities in the heel and forefoot for improved comfort. ASICS® High Abrasion Rubber (AHAR®) carbon rubber is located in the heel and offers exceptional durability. DuraSponge® is located in the forefoot and is a blown AHAR® compound that delivers cushioning, responsiveness and flexibility. Wt. 10.6 oz.
