E. Porselli ballet flats. I purchased these a few years ago at an A.P.C. directly managed store. The size is 37. My foot size is 23cm, and I usually wear 23.5cm for flat shoes, but these fit just right with a little extra room. The soles were made of delicate leather, so I had rubber soles attached at a shoe repair shop in Nihonbashi, and I wore them for a while with non-slip insoles in the arch area. The leather is soft and easy to wear, but I'm selling them because my clothing style has changed. Since I wore them regularly, there is overall wear and tear. For example, the insole is white only in the arch area where I placed an insole, while the toe and heel areas are darkened. Also, both toes have some scuffing, possibly from bumping into things. Please check the photos. One thing I'm concerned about is that, since I bought them, I've felt a sort of "squishiness" when walking, like stepping on a piece of paper. I think this is because the sole is made by layering leather, creating a mille-feuille-like gap, and it crinkles when walking. I don't have any other Porselli shoes, so I don't know if this is a common phenomenon, but there's no sign of them breaking or peeling, and it shouldn't be a problem if you don't mind it. Please be aware of this. Overall, they are very comfortable to wear, and the rubber soles are securely attached, so you can continue to use them for a long time. They are good quality, and it's a shame to throw them away just because my style has changed, so I'm putting them up for sale for a short period.
