Insulated boots....

You want a good boot? Try Mickey Mouse boots or sometimes referred to as Bunny boots.

The one thing you must be careful of is not to tear the rubber. Wear a regular pair of socks and you're good to go.

I can sit for 8 hours with my feet on the ice when ice fishing, and my feet stay just as warm as can be.

The one drawback is they are somewhat bulky. You should be able to get them at a local Army surplus if you have one.
