Adjustable Fins FAQ

The main questions about the highly adjustable fit of shinfin™ leg fins, are answered below. Or you can go to the complete FAQ list.

Do fins fit people with small feet or narrow feet?


shinfin™ leg fins easily fit people with small feet and/or narrow feet. So, even if you have small feet and/or narrow feet and/or a low arch, the fins will still fit you.

The fin doesn’t enclose your foot at all. It straps just above your ankle. The lower part of the fin lies gently along the top of your foot. It doesn’t attach to your foot.

They still fit if you have unusually shaped feet. The size and shape of your feet doesn’t affect how they fit. You can wear them whatever your foot size or shape. Foot amputees can wear them too.

With particularly small feet the fins might stick out a little more from your toes. This doesn’t really affect your swimming. But it can make walking a bit harder (although still better than with foot flippers!). If it bothers you, then you can just fit the fins a bit higher up your legs.

Do fins fit people with large feet or wide feet?


shinfin™ leg fins easily fit people with large feet and/or wide feet. So, if you have large feet and/or wide feet too and/or a high instep, the fins will still fit you.

The fin doesn’t go around your foot at all. The lower part of the fin lies gently along the top of your foot. It doesn’t attach to your foot in any way. The fin only straps just above your ankle.

So it doesn’t matter if you have large feet, wide feet, high insteps or unusually shaped feet. Your foot size and shape doesn’t affect how they fit. They can be worn by people with any foot size.

Do fins fit people with narrow calves and thin legs?


The centre of shinfin™ leg fins flexes inwards to fit people with narrow calves and/or thinner lower legs. So even if your lower legs are very thin and/or your calves are very narrow, the fins will still fit you.

They match your leg shape by bending around your shin. You can adjust the fin height on your leg for the most comfortable fit.

The straps go around the narrowest part of your leg, just above your ankle. So please measure the circumference around this narrowest part. If this circumference is 20-40 cm (8-16 inches) then the standard straps supplied with the fins will fit you.

If this circumference is less than about 20 cm (8 inches), then the fin centre may not bend inwards quite enough. Then you may like to wear your fins over a wetsuit. The wetsuit effectively thickens your lower leg.

Do fins fit people with large legs & broad calves?


The centre of shinfin™ leg fins flexes outwards to fit people with broad calves and large legs. So, if you have large legs and/or very broad calves the fins will still fit you.

They wrap around your shin to match your leg shape. You can also slide them up or down your leg for the most comfortable fit.

You just need to check which fin strap length you need to fit you.

The straps go around the narrowest part of your leg, just above your ankle. So, please measure the circumference around this narrowest part. If this circumference is 20-40 cm (8-16 inches) then the standard straps supplied with the fins will fit you. If this circumference is larger than 40 cm (16 inches), then just select the option for longer straps when you order your fins.

Do fins fit small people with short legs?


shinfin™ leg fins fit very well on short legs, for small people. So, even if you are a small person about 140 cm (4 feet 7 inches) tall and/or with short legs, the fins will still fit you.

I normally say the one fin size fits everyone over about 140 cm (4 feet 7 inches). But actually, they will still fit you even if you are a bit shorter than that. Having shorter legs doesn’t really affect how the fins fit on your legs. Whatever your leg length, the straps still go around your leg just above your ankle. The straps are also highly adjustable to fit you properly.

Do fins fit tall people with long legs?


shinfin™ leg fins fit very well on tall people with long legs. So, even if you are a tall person about 200 cm (6 feet 6 inches) tall and/or with long legs, the fins will still fit you.

Being tall doesn’t affect how they fit on your legs. This is because the fins fit at the bottom of your legs. Having a long leg length above the fins doesn’t make any difference to how the fins fit your leg. The straps adjust easily to fit around your leg just above your ankle.

Do fins keep fitting a growing child to adult size?


shinfin™ leg fins with standard straps will almost certainly keep fitting children through to adult size.

So, you don’t need to keep buying new foot fins every time your shoe size changes. If you are still growing, these fins will keep fitting you.

They fit regardless of foot size and shape. The fin centre flexes inwards to fit younger, thinner legs and flexes outwards to keep fitting as you get older and your legs grow larger.

The one size easily fits everyone taller than about 140 cm (4 feet 7 inches) up to very tall people. They actually still fit if you are a bit shorter than this, but they may stick out a bit more from your toes. Swimming with them is still fine. Walking might be a bit harder but will get easier as you grow.

The standard straps fit most people up to large adult size. The straps go around the narrowest part of your leg, just above your ankle. If this circumference stays within the range 20-40 cm (8-16 inches) then the standard straps supplied with the fins will keep fitting you. But if you expect that this circumference will become larger than 40 cm (16 inches), then just select the option for longer straps when you order your fins. Or you can order longer replacement straps later if you need them.

Can fins be worn with and without wetsuit?


The centre of shinfin™ leg fins flexes to fit people both with and without their wetsuits. You just need to check that you select long enough straps to fit over your wetsuit too.

So in warmer water, you can wear them without a wetsuit. When the water is colder, you can adjust the straps to wear them over a wetsuit. The fins still fit.

The straps go around the narrowest part of your leg, just above your ankle. So, please measure the circumference around this narrowest part whilst wearing your wetsuit. If this circumference is 20-40 cm (8-16 inches) then the standard straps supplied with the fins will fit you. If this circumference is larger than 40 cm (16 inches), then just select the option for longer straps when you order your fins.

If you prefer to measure your leg circumference without your wetsuit, then just add the following to your measurement to compensate. For a thin 3mm suit add 2 cm (1 inch). For a thick 8mm suit add 5 cm (2 inches).

Are fins easy to share with friends & family?


shinfin™ leg fins are easy to share because they adjust to fit a wide range of people of varying heights, builds and foot sizes.

With regular foot flippers, people with different foot sizes each need a different foot flippers size to fit them.

With shinfin™ leg fins, foot size doesn’t matter at all. They fit you regardless of your foot size. Your foot size doesn’t matter.

They also adjust to fit different leg sizes and shapes. The one size easily fits everyone taller than about 140 cm (4 feet 7 inches). They still fit if you are a bit shorter. They just stick out a bit further from your toes.

Fins easy to share with family and friends can save you a lot of money too.
