Follow-up question: I went to the only Dutch store that sells Corthay to order a pair of Wilfrids. Sadly, they didn't have any pairs in my size to try on, so I didn't end up ordering any. They also informed me that Corthay was unwilling to accommodate requests for two different-sized shoes. Now, I find it difficult to believe that you couldn't get two different sizes from Corthay when ordering MTO, but before I plan a trip to Paris to visit Corthay I'm curious to know what your experiences are? Thanks!
