CanDo Inflatable Exercise Ball With Stability Feet

CanDo Inflatable Exercise Ball With Stability Feet has stabilizing feet that keep the ball from rolling when not in use. When in use, the weight of the person makes the feet retract into the ball so it can function like any other inflatable exercise ball. Non-slip surface is ribbed for extra security. It can be under inflate to give a soft, mushy feel or fully inflate for a firm, bouncy feel.
