Simple design but aggressive, a bit less so in the SuperSoft. On the surface it’s just 2 balls but consider that each one is done in an oval so that even though they will fit a bit more comfortably one way, turn them the other way for a tougher entry. The small ridges add an intense stretch at the apex of each hump too. Solid square base for hands-free play. The max circumference above is taken at the ridges which jump about 3/8″ in circumference from the surrounding surface.
