Had them added
to my original drysuit. My winter paddling frequency went WAY up after that.
I suffer from cold feet year-round, and having dry feet and lots of wool on them makes it tolerable at least in the winter.
I’m thought about buying some nice
waterproof boots/mukluks, but when I saw the prices, I got cold feet again. 
They really aren’t that expensive, I’m just hoping for an end of season sale in the coming months.

Ditto on Chota…
mukluks. Mine keep my feet warm Autumn through Spring. Yes I get out in winter as well!
