The Asics MetaSpeed Sky+ men’s road racing shoes are made for stride-style runners to elevate your speed and preserve your energy. They partner smoothly with runners seeking to move more efficiently and faster with a longer stride. The Jacquard mesh upper allows your feet to breathe during high-speed training. According to Asics a minimum of 20% of the upper is made of recycled polyester, keeping your carbon footprint lighter on the environment. FF Blast Turbo cushioning compresses underfoot and couples with the carbon plate to create a snappy sensation on toe-off. The carbon plate shape and placement, the stack height, heel-to-toe drop and toe spring have been sculpted specifically to meet the demands of 'stride' runners. Stride runners are those that generate more speed through a longer stride. The hard-wearing ASICSGrip outsole provides traction and durability to unlock your running potential. - Engineered for stride-style runners to put your best foot forward during training and racing - Lightweight and breathable Jacquard mesh upper - Upper is made in part with recycled polyester - More eco-friendly dyeing process of sockliner - Responsive FF Blast Turbo cushioning - Carbon plate for a propulsive feel and guidance as you transition between strides - Curved sole for a smooth, energy-efficient stride - High traction ASICSGrip outsole to cut seconds off your personal best
