These boots don't have zippers, which means that the opening is small.  I have tried to put my socked feet through these boots and have failed.  My socks get stuck in the opening and this is an IMPOSSIBLE TASK.  So, I am walking around in these boots in the  middle of the winter with bare cold and sweaty feet.  By the way, even the shearling boots do not have shearling on the footbed (except my socked feet can make it thought the shearling boots).
