These shoes were sold as being made of enamel fabric, suitable for both rainy days and sunny days. The size didn't fit me well, so I attached cushions to the heels and wore them twice (less than an hour each time) on sunny days. Therefore, the soles of the shoes are still clean. I'm sending them as is because the heel cushions feel sticky if I try to remove them. Please be aware of this. ~For reference~ My usual shoe size is 23.5-24.0 cm. With the heel cushions in, they barely stayed on. When wearing tights in the fall and winter, they didn't come off at all.
