These are beautiful and unfortunately undersized for me (in volume not in length). I usually wear a 10.5 in US sneakers and a 43 in Birkenstocks. They are sold out everywhere in larger sizes and I jumped at them when I saw this single pair still available on Mr. Porter. Retail for $545. They are new only tried on in my pet/smoke free home. Priced to sell! Will consider all reasonable offers!
