Hello again. Here is my another idea, when it comes to HOMEMADE boots to walk in the water.
Maybe you have seen my first instructable https://www.instructables.com/id/Fishermans-boots-homemade-high-wellingtonswelli/
. I think it's good, but not long lasting. That's why I came with this idea.
Again, it is very cheap ... less then 1GBP :)
