Below Knee Amputation Swim Fins (BKA)

shinfin™ swim fins are used as below knee amputation swim fins by many people around the world. They give very positive feedback. It depends on the person of course, but many below knee amputees can pretty much get back to swimming as normal with shinfin ™ swim fins. They enjoy them and find them very beneficial. Good hip movement helps and shinfin ™ swim fins help you to develop this too.

Yes, you can fit shinfin™ swim fins on your lower leg stump(s). The fin centre flexes open to match your stump size and shape. The rubber straps grip well around your stump, to stop the fin slipping off. The fin fit is very versatile. You can also adjust the fin position to optimise your kick.

Fin size for below knee amputation

There is only one size of fin and they will fit you fine. It is only the length of the straps that you need to decide. You select the strap length in the drop-down list when you order your fins. Follow the instructions below, to measure around your legs in the correct places.

Fitting swim fins on your lower leg stump(s)

If your lower leg stump is about 15 cm (6 inches) or longer, this should be fine for fitting the fin. Fitting the fin on your lower leg stump is probably the best position if you can, because your knee joint helps to control the angle of the fin a bit more.

If your lower leg stump is shorter than about 15 cm (6 inches) and/or is very tapered, the fin may tend to slide down your stump when you swim. Then there are a number options, depending on your needs and preferences.

For example, a neoprene stump-sleeve can increase the grip of the straps around your leg. That is perhaps the first thing to try. Or you can slide the fin up so the straps cross behind your knee joint. In which case, you might also like some extra padding behind your knee, such as an extended neoprene stump-sleeve or a wetsuit. If necessary, you can also trim the leading edge of the fin with scissors.

Alternatively, you can fit the fin on your thigh with the straps just above your knee (as for above knee amputees). We have below knee amputee customers doing both. It depends on your body flexibility and joint movements as to which is best for you. You can experiment with this, and also with the angle of the fins around your legs.

Single below knee amputation swim fins

Single above knee amputees should wear a pair of shinfin ™ swim fins .

Wear the first shinfin ™ leg fin on your lower leg stump.

Wear the second shinfin ™ leg fin on your other shin. Position the fin tips at your toes, or perhaps a bit higher. By the way, it is not advisable to wear a foot flipper instead. That will disturb your stroke balance and power because a foot flipper requires a different biomechanical kick action. It requires more knee-bend with power from your calf muscles, instead of a straighter leg kick with power from the large muscles in your thigh, buttock and torso. A foot flipper would also strain your foot, ankle and calf muscles.

I strongly recommend wearing a pair of shinfin ™ swim fins, as above. Whilst you could just wear only one fin, on your lower leg stump or on your other shin, having a fin on each leg gives you best stroke balance and power. That is what nearly all of our amputee customers do, if they can. Fit the first fin on your lower leg stump. Fit the second fin on your other shin.

Bilateral below knee amputation swim fins

Bilateral below knee amputees should wear a pair of shinfin ™ swim fins , one fin on each lower leg stump.

Strap lengths

Measure around your legs where you want the swim fins to strap on, to see whether longer strap(s) may be needed. For a fin on your shin, measure around just above your ankle. For a fin on your lower leg stump, measure around your stump about half way up. If you have a shorter stump, as discussed above, then measure around just below your knee cap and also measure around your thigh, in case you end up wearing the fin on your thigh.

If your measurements are 40 cm (16 inches) or less, then the standard length straps that come with the fins will fit you. Any longer requires a long strap. Select your strap lengths when you order your swim fins: standard, long or mixed (one standard strap and one long strap). You can also order spare pairs of straps with the same length choices. You can cut straps shorter with scissors later, if needed.

Stroke power & balance

shinfin ™ swim fins give you extra kick power and speed through the water. The fins can be worn in different positions on each leg. So your objective is to balance the down kick of one leg with the upkick of the other.

The swim fins will also help you to get more power from your arm strokes. This is because your left leg kicking down, diagonally balances the force of your right arm pull, and vice versa. You can also experiment with the height and angle of the fins around your legs, to optimise your stroke.

They encourage you to use the large muscles in your thighs, buttocks and torso. So they help you to build muscle tone in these areas. This is likely to benefit your movement out of the water too, as you will know.

Streamlined swimming

shinfin ™ leg fins also encourage and stabilise a streamlined body position. The fin positions and angles on your legs, lifts your legs and body more horizontal to reduce drag, even for slow kicking and gliding.

The fins will help to lift your legs to a horizontal streamlined swimming position, on your front or on your back. This works even if you don’t kick and just swim a little with your arms. Then, if you start kicking, the fins will guide you towards a streamlined swimming kick. They achieve this because they have a natural flex that matches a good kicking style for freestyle, backstroke and fly.
