Vintage 1980s Sporto Women's Blue Rubber Boots Thermolite DuPont Certified Sz 7

Vintage 1980s Sporto Women's Blue Rubber Boots Thermolite DuPont Certified Ankle High Size 7. Boot are vintage pre-owned from 1980s. These were my MILs. She had several pairs of these and this was the only one left I found in her closet. I know they are from the late 1980s because she bought me the same pair back then. Lace up. Minimally worn. Has the original box but it is pretty beat up because it was on the bottom of a stack of other boxes of shoes. I will not ship the box unless you specifically say you want it. Has faux fur inside. These are heavy and thick. They are stiff too - keep in mind the age. There are some brands that don't age well but considering these are rubber they should be ok - they don't look like the are failing material wise.
