VTG 80s Sporto AC Insulated Quilted Zip Front Cold Weather Booties, 8.5

Vintage 1980s era red quilted and insulated cold weather booties from Sporto AC. Zip front. Slight wedge heel. No size tag, would probably fit a size 8.5 best. I wear a size 8.5-9 and they fit me snugly, with thick socks on. There are some light darkened marks on the left shoe, and the rubber is a bit cracked above the sole of each boot. As far as I can tell, it doesn't look like the cracks go all the way through though. Booties as as-is.
