SwimFin is designed around simple principles of buoyancy, balance, and natural movement.
This page explains how its unique design supports swimmers as they build confidence, technique, and independence in the water.
You don’t need to understand the science to benefit from it but it’s there, working quietly in the background.
SwimFin is worn high on the back, above the swimmer’s centre of gravity.
This position gently supports the body in the water without forcing it forward or upright, keeping the chin on the water level.
Unlike armbands or vests, which lift from the arms or chest, SwimFin helps the swimmer find a natural, balanced position.
Arms remain completely free allowing proper movement from the very beginning.
When a swimmer is more upright, SwimFin is deeper in the water.
The greater the submersion, the more buoyancy it provides, offering reassurance and support to beginners.
As the swimmer becomes more horizontal, the fin naturally rises out of the water.
Less of the fin is submerged, so less buoyancy is provided which encourages balance, body position, and independence.
No adjustments. No inflation. No removing layers.
Traditional swimming aids provide constant upward lift. This means the swimmer is always leaning on the aid for support, which can slow the development of balance and natural buoyancy.
SwimFin works differently. Its support reduces automatically as the swimmer improves, allowing the body to respond naturally to movement and position.
This aligns with basic principles of physics: as the swimmer changes orientation in the water, the forces acting on them change too. The result is a smoother, more intuitive learning process.
(You don’t need to know Newton’s laws — SwimFin already does.)
Because SwimFin doesn’t attach to the arms or chest, swimmers are free to move naturally.
This allows:
That’s why SwimFin can be used across freestyle, backstroke, breaststroke, and butterfly, from beginner lessons through to advanced technique refinement.
Support changes automatically as the swimmer improves.
Nothing to add, remove, or modify while swimming.
Progress happens through movement, not reliance.
SwimFin is suitable for swimmers from around 18-24 months through to adults. Its adaptive design allows it to support different body sizes, abilities, and learning speeds.
Many instructors also use SwimFin as a valuable tool for swimmers with additional needs, where confidence, balance, and freedom of movement are especially important.
SwimFin has been designed, tested, and manufactured to meet both international and Australian/New Zealand safety standards.
Its position on the back keeps the face clear of the water, while its secure straps ensure it stays correctly positioned during use.
SwimFin is trusted by families, swim schools, and instructors worldwide.
