• A powerful fin by nature. Its rigid, robust blade is delicately balanced by the special elastic centre membrane, which is designed to channel water backward, giving more speed and power to get on top of the conditions.
• The angle of the blade - in relation to the foot pocket - is designed with efficiency in mind. As each stroke begins, the fin provides ample propulsion without straining the muscles.
• Rubber grip under foot pocket prevents slipping on deck or similar surfaces 
• Underside foot pocket drain hole for water drainage.
• Quick release buckle makes putting on and pulling off easier and faster.

FOUNDED 1976 Company founded in Taiwan. Siblings Irene, Stanley and Tony Lin join together to form IST. Named after their combined initials, the company symbolized a community effort to work together toward a better future. When IST was first established, their primary products were windsurfing boards. As more connections to the diving community began to emerge, boundless opportunities within this new market opened up. IST began manufacturing diving boots as an introduction into the scuba diving industry. IST began releasing a broader range of diving equipment, including masks, snorkels and fins. As a pioneer in the market, they produced great quality at more affordable prices, earning high praise from their new customer base.
