Hi Ash,
I have to agree with evryone, stocking foot waders will be uncomfortable because of the sand getting into the boot plus other things.
Ash, they are having a great sale at Betty & Nicks till March 1st. you should be able to pick up a good pair there and they will not steer you wrong. I like the pair I have and before you get them make sure you try them on before you buy.
I had to go up in shoe size to get a more comfortable pair. Just a hint.
Happy Catching
Paul
