Air Cushion Festival Basement Tabi Shock absorbing reduces heel strain. The upper bottom uses the ultra-sole, a newly designed anti-slip design that provides strong non-slip performance not only in vertical directions but in horizontal directions on interactive surfaces such as water and oil film. (Ultra Sole has high slip resistance on smooth surfaces in dry conditions or interactive flooring surfaces such as water, oil and other surfaces, but it does not provide traction on all surfaces. In addition, there may be cases where there is no sufficient anti-slip effect due to wear on the bottom and clogging between the designs. )
