The monofin is the key component in the swimmable mermaid
costume as it is this piece of equipment which propels the
wearer through the water in a realistic, mermaid-like fashion.
Therefore, it is very important that you buy a monofin which is
durable, well fitted and of a high quality.
Although you have the option of taping or tying two separate
flippers together to create a monofin, the best option is always
to buy a monofin as it is designed specifically for the dolphin
kick style of swimming. Your monofin should be flexible but
secure, allowing you to swim through the water in comfort.
Many different types of monofin exist, but the best option for a
mermaid tail is the classic monofin. These are very lightweight
and have classic foot pockets, ideal for those who have never
practiced finswimming before. Try to find one with an adjustable
strap behind the heel, as this allows you to adjust the fitting
of the monofin so it is both secure and comfortable on your
If possible, try to find a fibreglass monofin as this material
tends to be the most durable – thereby giving you the best value
for money, even if it is a little more expensive than the
alternatives! Many monofins are made of thermoplastics which not
only tend to be of poor strength and crack after bending, but
also tend to be a little more rigid than their fibreglass
counterparts meaning that the fluid movement of the mermaid tail
may be compromised.
In terms of fitting, the foot pockets should be tight but not
overly so as this can cut off blood circulation to the feet.
Remember that most people have a slight variation between the
sizes of their left and right feet, so always try before you
buy! Choosing the right size of foot pocket is massively
important, so take the time to consider which is best for your
needs and which will go best with your mermaid tail.
