I were the knee high type rubber boots for hunting around here because of all the swamps,I am getting sick of them because they are so hard to get on.I am a big guy and some rubber boots I cant even get on because the calf isnt big enough.I use grocery bags to get my feet in most of the time but if I walk more than a 1/4 mile my feet hurt because of all of the sliding that they do in the boot from the slickness of the bag.I was thinking of trying a silk sock or something to get my foot in easier.I just bought the boots so Idont want tobuy another pair,but I treid some of the side zip 800 grams thinsulateones at bass pro and they fit great.I would like to get one with a little more insulation for the cold winters here.Can someone tell me were I can get a side zip knee high boot with at least 1200 grams of thinsulate or an easier way to get the ones I have know on?
