From their website:
Founded in 1993 in Northern California, FINIS was founded by John Mix and Olympic Gold Medal Swimmer Pablo Morales. Understanding that improving one’s technique is the secret to swimming faster and enjoying the sport more, the duo went on to introduce truly innovative tools to the swimming community. Many of these products are currently used by US and international Olympic teams, elite Triathletes, and fitness swimmers worldwide.
Innovative research and design is FINIS’ highest priority. This dedication has resulted in truly innovative products such as: the Swimmer’s Snorkel which is recognized as the paramount tool to improve a swimmer’s technique, the SwiMP3 that uses bone conduction technology to play music instead of using ear buds, and the Z2 Zoomers fins which demonstrate intimate knowledge of swimming musculature, hydrodynamics and engineering.
