MAXIMUM TRACTION  Sharp, square lips provide maximum grip while still sliding smoothly when desired. HAPPY THANE The original Orangatang urethane formula is smooth, plush, and grippy with a buttery-smooth slide. LARGE, SUPPORTIVE CORE The fully exposed 46mm core reduces weight while providing quick acceleration and crisp slides.
