For athletes that like to mix it up for their training routines, the ASICS GEL-Quantum 180 TR is the perfect training shoe. This supportive yet lightweight shoe allows for explosive agility and efficient strength-based movement making it a highly versatile tool. Hitting the track for drills and interval sprints also comes easy with the help of the responsive Rearfoot and Forefoot GEL® Cushioning Systems. Upper: Seamless synthetic leather and mesh construction supports the foot, reduces the potential for irritation and friction, and enhances breathability. Midsole: Rearfoot and Forefoot GEL® Cushioning Systems attenuate shock during impact and toe-off phases, and allows movement on multiple planes as the foot transitions through the gait cycle. Solyte® Midsole Material is lighter than standard EVA or SpEVA® and features enhanced cushioning and durability. ComforDry™ X-40 Sockliner and Lasting feature higher rebound properties while providing excellent moisture management, high-level breathability, and antimicrobial properties. Outsole: Full-length Trusstic System® reduces the weight of the sole unit while retaining the structural integrity of the shoe.
