Brand new, never worn (other than to try on at home, on carpet) ballet flats from The White Ribbon, a bespoke German brand. The whole shoe (upper, insole, and sole) is made from very buttery leather in a gorgeous pale white-gold color that is currently sold out on the retailer's site. They're suuuuper comfortable and good for wide feet. Unfortunately, I accidentally ordered a size too large. It took them three months to get to the U.S. from Germany, so I'd prefer to resell rather than return.
To help determine whether these will fit you, TWR recommends carefully tracing around your foot and then measuring the length at the longest point and the width at the widest point. The measurments for length and width of this shoe are: U.S. 7 (EU37) Foot length: 24 cm/9.44" Foot width: 7.7 cm/3.03" (TWR notes that if your feet are 1-1.5 cm wider than the measured width they'll still fit, and I've found that to be true.)
