Professional, laced men's Asics Gel-DS Racer VII training shoes designed for running, although they will also work well in general physical activity. They have been equipped with many technologies that improve both performance and comfort of use, such as: Gel-Cushioning, DuoMax, I.G.S and AHAR+.The first system involves the use of a mixture of synthetic materials such as rubber, gel and others in the sole of the shoe. This solution ensures low own weight and high quality cushioning. Due to the fact that the sole is able to disperse vertical impact energy and convert it into horizontal, it is able to absorb much stronger impacts. I.G.S. (Impact Guidance System) is a technical solution used in the construction of the shoe, thanks to which the possibility of natural foot movements is maintained. The I.G.S. system facilitates maintaining a natural gait and run.FluidRide is the result of ASICS' evolution in the area of midsole technology, providing exceptional lightness and cushioning. Thanks to this technology, runners can cover longer distances at a faster pace. Changes made to the midsole allowed the use of a new, higher density SpEVA 55 insert, which together with the reinforced heel provides the best rebound characteristics and cushioning while maintaining lightness. DuoMax is based on the use of dual density foam for even better cushioning and maximum comfort for the user.The outer upper is made of a combination of breathable textile material and durable synthetic material. The inner upper is made entirely of soft textile material ensuring adequate comfort. The outer sole is a 100% mixture of various synthetic materials providing adequate cushioning covered with a special Ahar+ rubber mixture, which is exceptionally resistant to abrasion and extremely durable.
