Swim Training Fins: clubs, masters programs, coaching squads, drills & sets

What are your ideal swim training fins?

Are you a good/elite swimmer, or coach, interested in swim training fins for speed and endurance? Is your swim club or squad open to a new swim training fin? Perhaps your masters swimming program would benefit from this new approach? Are you looking for more benefit and variety in your drills and sets?

Good swim training fins must work with your natural swimming stroke, otherwise they can do you more harm than good. They should “feel right” when you wear them. All your body movements (arms too) should be similar to your natural stroke. You should use the same muscles, in the same muscle sequence as your natural stroke. Your swim training fins should always “feel right” even when you swim slower (perhaps to work on your upper body technique), or swim faster (perhaps with a higher beat kick). When you take them off, your natural swimming stroke must return immediately without adjusting your stroke. Then you know your swim training fins are enhancing your natural stroke rather than corrupting it.

I have designed shinfin™ leg fins to offer you all these swim training advantages, and more. They achieve this by connecting power directly to your legs, above your ankle joints. Your feet and ankles are free to move normally and you swim with your natural stroke. Foot flippers cannot work with your natural stroke (even if you cut them short across the toes) basically because they are connected to your feet. This is why they are a swim training fins evolution from all foot flippers (even short training fins).

Train your natural streamlined stroke

Swim training fins ~ more from the inventor/designer

I have designed shinfin™ leg fins to match the natural streamlined kicks for freestyle, backstroke and butterfly. Since about 1990, I have developed over 50 prototypes. Testing has included beginner and intermediate swimmers through to elite swimmers at the Australian Institute of Sport and in the Australian Olympic Team. Testing has also included physically and intellectually disabled swimmers. I have studied swim training with leg fins, with foot flippers and without any fins, using underwater video equipment and biomechanical analysis.

Good and elite swimmers and swim coaches quickly recognise the natural, streamlined kick of shinfin™ leg fins and their swimming training benefits. You feel how they help to keep your body horizontal for less drag. You feel how they guide you to kick from your hips, with only a little knee-bend. You feel the power coming from the big muscles in your upper legs, buttocks, stomach and torso. These are same muscles you use for good “no-fins” swimming (without straining your feet, ankles and calf muscles like foot flippers). You also feel how they give the correct body balance to support your arm stroke. So you know your swim training with shinfin™ leg fins is strengthening your natural kick – you can feel it. That’s why they also improve your “no-fins” swimming technique (arms too), stroke efficiency and speed. They are biomechanically advanced swim training fins, an evolutionary step up from all foot flippers (even short, training flippers).

Most swimmers and coaches know that foot flippers corrupt your kick. Foot flippers cannot give similar swimming training advantages simply because they attach to your feet. They stiffen and cramp your feet and ankles, and disrupt water flow. Foot flippers change your body position and your ankle, knee and hip movements, often to a “bicycle-kick” with knees bent too low. You can’t kick at your normal rate and you use different muscles. You know your swim training is wrong because your body remembers the corrupt foot flipper kick even after you take them off. That’s why it takes a few laps without foot flippers, before your stroke feels natural again. Some coaches cut foot flippers short to try to improve them, but they are still connected to your feet so the problems remain. Other coaches refuse to use foot flippers at all for swimming training.
