An unusual style of Casadei black leather OTK boots

eBay boot seller "livefire" sold these very nice Casadei black leather OTK boots for $228.  These Italian-made boots were a size 10 and appear to be in excellent condition. 

These sexy boots originally retailed for $1,200 and featured a very nice 4.25" narrow stacked high heel, 20" tall shaft, classic almond toes, and an unusual zipper detail on the outside of the boot.  These boots also came with a dust bag.

I have to admit, I've seen many styles of Casadei boots, but never this particular style.
