The Lattanzi's were a one time deal/VERY limited production in the late 1990's. Yes, PLEASE be aware that if you buy a pair of Jil Sander shoes, the chances of them being Lattanzi's are VERY slim. Most of the shoes marked "Jil Sander" were produced after Prada purchased them in Prada's facilities. In fact, much of the reason why Jil Sander herself was excited about joining Prada group was because of the promise by Prada to help build the accessories branch of the brand.
The quality of these Prada produced shoes, while slightly better than Prada, nevertheless isn't so great. The Lattanzi-produced Sander's are wonderful (sometimes oddly designed, but amazing quality), but they were $2000+ while most Sander's are $350-500. Plus, they will have hand-written labels on the inside vs. the regular Prada produced models which simply have the "JILSANDER" logo stamped inside.
The Church's deal is CURRENT, only from the most recent season after Raf Simons took over the design from Jil herself. So, if you purchase a pair of shoes in the boutique NOW, it is possible that they will be made in England. But, Yoox is always a year behind, so they're selling shoes produced just after Jil quit and just before Raf took over, when a Prada Group design team took over for the interim.
Chris Italia... be careful throwing the "Lattanzi" badge around, especially with Sander. Of the probably 50,000 pairs of Jil Sander shoes produced between 1998-2006, probably less than 1% of those are Lattanzi. And, Lattanzi hasn't produced a Sander shoe since at least 1999 or 2000. When Prada bought Sander, all those expensive collaborations and deals went out the window at the behest of Bertelli, the Prada CEO (this is much of the reason Jil herself quit the first time in 1999).
Kali77 is correct; that picture is of a Lattanzi Sander. I've been lucky to score a few pair on the new over the past few years; they're really odd but spectacular shoes.
