Are you tired of your swim fins aching your feet and causing blisters on your feet.Well I was sick of it and came up with a solution to make your fins comfy without spending too much cash.Here is what you will need:

Two silicon swim fins(any size maybe get a size up if you are at the max of your current size).
1-2 lightweight athletic shirts(I recommend using an old t shirt that you don't wear).
Duct tape(White or Gray)

Step 1: Step 1:Preparation

What you want to do is cut off a piece of fabric from the shirt to fit either the left or right side of the fin where you would put your foot not your toes.After that do the other side it is okay if you have some access cloth.Then put a piece of ductape that fits the cloth's top,bottom, and sides attach it to both pieces of cloth.

Step 2: Step 2:Attaching

The image above shows what one can side look like when done

Attach the pieces to the fin make sure their is no air bubbles between the cloth and fin.Once, you have done that reinforce so that the fin's rim has only ductape on it (reinforce it with your foot in the fin).Then put a cross from ductape to reinforce the fin.If you notice you need more tape somewhere feel free to reinforce it.
