Look up dans hunting gear on the Internet. They have some boots on there they call frog legs (hip waiters). They have a pair that a snake proof. I wouldnt trade mine for anything else.
I like the Dan boots. I have a pair of lacrosse alpha sports I have walked rice in for 3 years. Dans offers the same boots with the thigh high snake chaps attached. This is the boot I intend to buy as soon as I can.
