Stiga Vertical are a series of long pips developed in close collaboration with former Japanese National Team player Masato Shino. The pip structure for Vertical 20 and Vertical 55 is placed at a vertical angle providing extra control and stability in your defensive strokes. These rubbers are made in Japan and developed specifically to increase the spin of your chops for the modern defensive game. With a vertical pip structure and a 55 degree sponge hardness, it is Masato Shiono’s personal favorite.
