i wear muckboots pretty much year round. I double-sock. I buy cheap socks from Target for the outer layer. The double sock method keeps rubbing at the heel at a minimum (for me…my foot shape and my choice of boot…which is roomy!). My yoga instructor has a ‘thing’ against toes being squished together…so when putting sock ontop of sock, i pull at the toe and make space. (sort of like pulling a saddle pad up into the pommel). With this double sock and muckboot i can work outside during the coldest winter for hours and not get froze-toes. I have silk liners i use in the winter btw. For gloves too… And body also. Silk-silk-silk, then any ole thing…even cotton.
I learned double sock while on deployment. We have to wear gawdawful steel toe boots (govt issue) and they are notorious foot killers. Took one 10day deployment and crippling blisters for me to learn how to do my feet right.
