Jeff has transformed his snorkeling with shinfinTM fins strapped to his variation of osseointegration prosthetic legs for his bilateral below knee amputations. He kicks using his upper leg muscles with a straighter knee. So the fins really help him to get more horizontal on the water. Furthermore, this minimises drag and gives him smoother, more efficient snorkeling.
He loves shinfinTM fins as they are. In addition, he is considering ways of lowering drag and increasing thrust still further. This includes adding flotation to his osseointegration feet, as they are rather heavy and tend to sink. It also involves experimenting with strapping the fins at different heights to counter the drag from the fixed ankles of his osseointegration feet. Customers with fused ankles also optimise the height of the fins on their legs, for the same reason.
Jeff’s review from Denver, USA
“shinfinTM fins have transformed my ability to snorkel. We used them every day on our vacation. What I noticed the most is that they really helped get me horizontal on the water. Love them as is.”
