over the years i have tried just about every boot there is,all of them failed misserably for keeping my feet warm on stand becouse my feet swet somthing fearse.the mickey boots you refered to will keep your feet real warm if you put them on after your in the stand.this means you will have to carry those and wear somthing lighter while walking in.those boots are big and heavy to carry ontop of all your other gear,not an option in my book.the boot blanket is about the cheapest way of going about it.wear a pair of light weight 800 + gram thinsulate-gortex boots(these work great for walking)with a good pair of wool blend socks(no cotton).after your on stand(be it in a tree or on the ground)put the boot blankets on and your feet will stay warmer for many more hours then they would with out them.
