These are Phoebe Philo's 25SS sandals. I saw them at Dover Street Market Ginza, but only one pair in a women's size was left, so I purchased them online from the official store. This size 42 was the last pair available in all sizes. I've only worn them once, to a nearby convenience store. Celine Maison Margiela Comme des Garçons Prada Miu Miu
