VTG Sorel snow boots blue fuzzy size 7? 6? 8? Please read

Check out these rad vintage Sorel snow boots!! Unfortunately there is no size tag but I have shown some measurements. For reference I am a size 8.5 and while I can get the boot on my foot, they do not fit me. So it must be smaller. Probably also smaller than 8 but please view my measurements. Boots in good shape. No rips, holes or tears. Interior liner comes loose. Maybe it is supposed to? I’m not 100% sure. These are vintage and made in Canada. Smoke free home.
