You can fit shinfin
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, so you will find them to be very comfortable fins. You can also adjust the fin height and angle around your stump, to optimise your kick.
Fin size for below knee amputation
There is only one size of fin. They will adjust to fit thin stumps and fit broad stumps 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.
See Sami’s story, a bilateral below knee quad amputee, who has been swimming with the one size shinfin
Fitting 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 wetsuit material 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.
Please contact me with any questions about fitting your fins to your lower leg stumps – I am happy to help.
Measure around your legs where you want the 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 regular length straps that come with the fins will fit you. Any longer requires a long strap. Select your strap lengths when you order your fins: regular, long or mixed (one regular 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.
Single below knee amputees
Usually, single above knee amputees wear a pair of shinfin
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 why I generally recommend wearing a pair of shinfin
Kick from your hips with a straighter leg kick. You get power from the large muscles in your thighs, buttocks and torso.
By the way, it is not advisable to wear a foot flipper instead of the second shinfin
Bilateral below knee amputees
Bilateral below knee amputees should wear a pair of shinfin
Stroke power & balance
The 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, without hurting your knees and without adding back pain. This is likely to benefit your movement out of the water too, as you will know.
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. See Anthony’s story about how shinfin
