I purchased these on Yahoo Auctions about 10 years ago. The soles had non-slip treatment from the beginning. The heels are believed to be original. I used them about twice, but they were too tight for my 2E size, so I put them away. Size is 24.5-25.0 cm, recommended for those with narrower feet. The condition is quite good. I am also selling other items. Priority will be given to the first person to purchase. No stains, tears, or odors.
