I purchased these on Yahoo Auctions for my daughter, but the width is a bit tight, and it seems like she wouldn't be able to wear them for long periods. I hope they can find a good home with someone who fits the size. Size 5 1/2 is about 23.5cm, but these would probably fit someone who wears 23cm perfectly. The listing mentioned that men could wear them, but I doubt an adult male could even get them on. (The opening is narrow. I almost considered cutting the edges.) I'm selling them for a little less than what I paid for them, including shipping. Here's the product details from the original seller: ◆ Size: 5 1/2W (The size is small, so I think it's for women, but it seems like men could wear them if the size fits) ◆ Color: Beige brown ◆ Measurements (approximate): Outsole 27.5cm, Height 16.5cm ◆ Please allow for slight variations. ◆ The actual color may differ slightly from the images due to the performance of the digital camera and monitor. ◆ There is no Danner logo inside the insole, so the insole may be missing. Also, gravel comes out from inside the insole. There are stains and fuzziness on the suede. There are no other stains or damage of particular concern, but please refrain from claims or returns as these are used items.
