Vento continues to improve with all new liner constructions using new materials in new combinations. Combined with the last elongation, Vento fits and performs like never before. The Vento 3D is reversed from Dragon. The soft material is injected first. The end result is hardness where it is needed for energy transmission and performance, and softness for unparalleled wrap and fit. Allows easy entry & exit and a great closure around the lower foot. Offers rigidity in the toe and heel for a solid interface and exacting energy transmission.
