Strokemakers were designed to improve your swimming stroke while limiting shoulder stress! They increase distance per stroke by disallowing early recovery; strengthen swimming specific muscles and muscles used in water propulsion; improve feel for the water due to the flow-through holes and flexible design; and exaggerate both correct and incorrect movements to aid swimmer and coach to make corrections (the bright colors make seeing the hands in the water easier for the coach as well).
