These are Jack Purcell slip-ons. Off-white, 27.5cm. From the official description: "JACK PURCELL" was developed in collaboration with the legendary badminton player "Jack Purcell," who was the world champion from 1932 until his retirement in 1945, and was born in 1935. With its then-highest level of functionality, it gained popularity for court sports such as tennis, badminton, and squash. The line on the toe is affectionately known as the "smile," and the heel label as the "mustache." Along with "ALL STAR," it is a masterpiece loved by people all over the world. This is a renewed version that newly adopts a cup insole and wave slit sole, achieving weight reduction, and is an easy-to-wear slip-on type. The upper canvas is washed, giving it a casual look that evokes the atmosphere of being worn at the beach. Color: White系 (White-based) Size: 27.5cm
