 Adrian borrowed a pair of boat shoes (with Herringbone sole) during his Davis Cup tournament win in the US and upon his return, convinced Dunlop to develop this high grip sports shoe.The original shoe was called the Volley OC (Orthopaedically Correct) and was worn by Rod Laver, Margaret Court, Evonne Goolagong Cawley, Ken Rosewall, etc.The Volley OC continued up until the 1970s when it was replaced by the Volley International which featured the three-stripe woven tape around the heel, side quarter panels which secure the tongue, and new look injection moulded rubber sole.
