Ugg VTG Suede Shearling Boots

Super warm rubber sole off white shearling lined caramel brown suede, side half zip - one sticks a little but works fine. These were my mom’s I was confused about the size cause she got them in the UK, I guess which says 8.5, but tag says US 10. I think they could fit US 9 or 9.5 depending on socks. I’m 8.5 & tried to make work w thick socks wasn’t terrible but had to face the music! Good VTG condition & comfy!!
