Disabilities | Above Knee Amputation (AKA) Fins

Need fins that fit on your thigh stump(s)? + Fins bend to fit your stump size & shape. + Same size fits children to adults. + Fit with or without a wetsuit. + Extra kick power. + Improve joint mobility. + Stabilise and streamline your body. + Balance your stroke. + Adjust position to optimise your swimming. + Your most versatile fins.

We have many above knee amputees using shinfin™ fins around the world and we get great feedback. Yes, you can fit the fins on your thighs – 15 cm (6 inch) stump lengths should be fine for this. Our above knee amputee customers really benefit from the fins, even without the knee joint to control the movement of the fin. Good hip movement helps and shinfin fins help to develop this too. You will probably find it best to fit them on the front of your thighs, but they can also be fitted on the back of your thighs. It depends on your hip flexibility and joint movements as to which is best for you. For bilateral AKA, one fin is worn on each thigh. For single AKA, one fin is worn on the thigh stump and the other fin is usually worn on the shin (but could be worn on the other thigh instead).

The fins give extra kick power, encourage and stabilise a streamlined body position, and lift legs horizontal to reduce drag (even for slow kicking and gliding). The fins can be worn in different positions on each leg, as mentioned above. The idea is to balance the down kick of one leg with the upkick of the other. The fins will also help get more power from the arm strokes because the left leg kicking down diagonally balances the force of the right arm pull, and vice versa. You can experiment with the height and angle of the fins around your legs to optimise your stroke.

The fins will help to lift your legs to a horizontal streamlined swimming position (on your front or on your back), even if you don’t kick. If you then kick a little bit, they will guide you towards the correct swimming kick. The shinfin™ fins do this because they have a natural flex that matches a good kicking style for freestyle, backstroke or fly. They encourage you to use the large muscles in your thighs, buttocks and torso and so help to build muscle tone in these areas. (Foot flippers are quite different as they require much more knee bend, and strain your feet, ankles and calf muscles).
