Vintage black leather thigh-high boots sell for $435!

A boot seller in Switzerland sold these vintage 1970s/1980s black leather thigh-high boots for a very impressive $434.83.  These 38.5 / US 8 boots featured very clean lines, almond toes, and a nice narrow, stacked heel.  Unfortunately, the seller did not list the brand but there is something with a turtle(?) logo on the photo inside the shaft.  Otherwise, the heels and insides look like vintage Italian boots.

These boots featured a very walkable 3.7" heels and an impressive 25" upper above the heels.  For as tall as these boots are, it does not appear that they are meant to be worn cuffed.

This is a classic, timeless style boot that I can see being worn with skinny jeans or a pencil skirt.
