Impressive vintage designer OTK black leather boots

Swiss boot seller "bootshopmauro" sold these impressive vintage designer OTK black leather boots for $139.06. These size 38 boots received 22 bids and measured an impressive 27" tall.  I wish the seller had listed who made these because they'd be worth seeking out.

I especially like the clean lines with no zippers and the straight "stovepipe" shafts with minimal stitching.
