Like new women’s FootJoy Boa golf shoes. All white size 7.5 M. The BOA® Fit System In 2006, FJ and BOA® Technology's collaborative development of a unique, heel-mounted solution signified a game-changing moment in their approach to fit. By integrating the BOA® dial into the heel of the shoe, BOA® and FJ designers were able to effectively develop a "down and back" fit that encompasses both the forefoot and heel. In action, the integration of the BOA® Fit System has been credited by many FJ + BOA® loyalists for providing a performance fit that offers precision, stability, and power.
