These are size S office sandals. (Of course, they're also recommended for everyday wear.) According to the dimensions, they are 24cm, but they fit me perfectly, and I usually wear 23cm sneakers. The widest part of my foot (the arch at the base of the toes) is 7.5cm, and the narrowest part to the heel is 5.5cm. The opening of the shoe is made of rubber and is 15.5cm long and 6cm wide. *Both shoes have stains on the front toe area and the soles, and the left shoe has a small tear in the leather on the front toe area. Please check the photos. Please only purchase if you understand and accept the condition.
