Paul Sperry, was an avid sailor with a passion for adventure. He was faced with a real-life problem that stood in the way of his passion: How to maintain traction on a slippery boat deck. Paul found his inspiration from his dog Prince. Noticing how he didn’t slip on ice, he turned Prince’s paw over to ﬁnd hundreds of small cracks and lines going in all directions. These became the inspiration behind his inventive non-slip sole and the world’s ﬁrst boat shoe.
