Here is an unusual and rare offering of John Lobb shoe trees. I bought a pair of John Lobb Barros at their boutique in the Hermes St Honore location probably 12 years ago years ago. These shoe trees are marked John Lobb Paris and are size Medium. They measure approximately 12 inches in length extended and 11 inches closed. The adjustment is via a gold plated sliding block with a set screw. Thes are in excellent conition as I see no evident wear. I do not see any of these deluxe John Lobb shoe trees on eBay nor as sold on eBay. Your John Lobb shoes deserve these authentic trees. I also have listed a pair of John Lobbb Perrier shoes and a John Lobb leather belt on ebay.
