A seller in Prague, Czech Republic sold these Maria Christina tall black leather over-the-knee riding boots for $95.00 plus $15.00 shipping. These size 39.5 (US 9.5) boots were made in Italy.
The style of these boots remind me of the Stuart Weitzman "Hilo" boots, only with a more rugged lug sole. These boots featured an unusual zipper opening near the rear tops. In hindsight, I wish I would have bid on these.
