Fins on legs = Feet are free


Revolutionary new fins

New fin evolution

shinfin fins fit on your legs. They do not attach to your feet at all. So your feet are completely free. That’s why they are very different to foot flippers!

Their unique natural fin design matches the kick biomechanics of elite swimmers for freestyle, backstroke and butterfly. So their streamlined kick from the hip replaces the old bent-knee kick of foot flippers. If you don’t already do a streamlined kick, they will teach you. (Some customers use them for breaststroke or “frog-kick” but they are not specifically designed for this.)

shinfin fins have many uses – the same uses as foot flippers, plus a few more. Most importantly, they give you many benefits over foot flippers. Furthermore, they are excellent for many disabilities.

Our tips and FAQ help you to get the best from them. Above all, fin reviews from customers around the world tell you how much people love them.

And of course, you can buy them from our secure online shop for delivery worldwide, with a 100 day money-back guarantee. I think you’ll love them too. Any questions just ask – I am here to help. Many thanks from Marc Lee (Inventor & Designer). Please read on…

Fin size explains how one size fits all kids to adults taller than 140cm (4′ 7″) and all leg shapes. Of course, your foot size doesn’t matter.

Fitting fins describes putting them on and taking them off. Also tightening, adjusting and positioning on leg for best results.

Kicking fins explains how they encourage a streamlined kick from your hips, with only a little knee-bend. In contrast, foot flippers need much more knee-bend, which increases strain and cramps.

shinfin fins are also excellent for disabilities because they fit on your legs (not on your feet). So they give you many new advantages for many different disabilities. Swimming and other water activities become much more fun, so you get more health benefits too.

You can use them with many disabilities. They work with bunions, club feet, fused ankles, foot amputations, below knee amputations (BKA), above knee amputations (AKA), bilateral amputees etc. Furthermore, you can even strap them to your arms with below elbow amputations and above elbow amputations. In addition, they provide real benefits for many movement disabilities such as Cerebral Palsy (CP), Multiple Sclerosis (MS), Parkinson’s Disease (PD), neuropathy and stroke complications.

They are invaluable for learning to swim, building muscle tone, regaining movement control, rehabilitation etc. That is why we get excellent feedback.

Avoid foot flipper problems

Thank you from Marc

I get so many emails about the issues people have with their foot flippers. Most likely you already know some of the foot flipper problems too.

Foot flippers cause problems because they fit on your feet. Firstly, they often don’t fit properly – too wide, too narrow, not enough sizes etc. So they hurt your feet. Secondly, they stress your ankles, strain your calf muscles and twist your knees too much. Thirdly, they change your kick to a “bicycle kick” with too much knee-bend. Furthermore, because they are heavy and bulky, they tend to fall off and sink. Often they break or rot. Of course, they also trip you up when you walk!

Leave all these foot flipper problems behind when you switch to shinfin fins, the exciting alternative to foot flippers. In contrast, shinfin fins have many benefits and many uses for most water activities and are ideal for many disabilities too. More fun in the water. Take the plunge and evolve!
