I too have a pair of Lacrosse Iceman boots. They are the warmest boots I have ever had, use them for ice fishing and stand hunting. The Lacrosse Bog boots are fairly light neoprene fit snugly at the ankle, easy on and off and come just up to the knee. Just make sure that you buy them big enough so you can get a good pair of sweat soaking socks on ifyou are doing a lot of walking.
