FINIS, Inc. Foil Monofin


The Foil Technique Monofin teaches the Foil Body Motion developed and made popular by Coach Bob Gillett. The Foil Body Motion utilizes the entire body to create a powerful and undulating dolphin kick through the water. The Foil Monofin promotes an equal use of up and down kicks for propulsion throughout the entire dolphin kick movement, increasing core and leg strength. Natural rubber provides a secure and comfortable fit.

Features and benefits of the Monofin

  • Smart Fin™ technology: proprietary combination of blade angle and hydrodynamic vents for a natural kick cycle with instant forward propulsion
  • Single blade design promotes development of the undulating foil body motion and propulsive dolphin kick
  • Technique channels control the flex of the fin and encourage correct foil movement
  • Large surface area: works core and leg muscles more than standard fins
  • Open heel and toe design increases range of motion, open toe space for the most comfortable fit
  • Lightweight construction: comfortable to wear for all ages and abilities
  • Lightweight blade allows multiple swimmers to safely swim in a single lane
  • Natural rubber provides a secure and comfortable fit



A legacy of innovation
John Mix had his first encounter with a monofin in 1988 during a semester abroad in Austria. Monofin in hand, John returned to the States convinced that this tool was the next big thing in aquatic sports. Throughout the years, the FINIS monofin has taken many forms, ranging from competitive to recreational. In 2010, FINIS collaborated with coaching legend and underwater kicking guru, Bob Gillett, to bring the Foil monofin to the market.
