Asics Men's DYNABLAST 4 Running Shoe is designed for fitness enthusiasts seeking comfort for their runs or training routines. ​A soft, engineered woven upper and mesh tongue improve the shoe's fit, comfort and breathability. ​ The midsole and outsole are engineered to target the ball of your foot and heel striking zone. This helps create a higher energy return and more bounce at a lower stack height. At least 50 percent of the shoe’s main upper material is made with recycled materials to reduce waste and carbon emissions. The sockliner is produced with the solution dyeing process that reduces water usage by approximately 33 percent and carbon emissions by approximately 45 percent compared to the conventional dyeing technology. It comes in 41.5 EU size and 400 denim blue/french blue color.
