For many MANY years I relied upon a pair of LL Bean winter pacs - the kind with the wool felt liner. Recently, maybe because of my age (50), I've found that the felt pac boots provide absolutely no support, and if I wear them more than for an hour or two - or with a lot of walking - they make my feet sore. They fit more like simple slippers, which didn't do me well worn on all day/weekend activities with the Scouts.
Because of that I decided to avoid the felt pac type of boot and since then have purchased a pair of
Sorel Conquest boots - boots that use Thinsulate insulation.
Unfortunately I haven't yet had a chance to wear them for an extended time yet ... but I think they'll work just fine.
