La Sportiva Theory EU40. Used about 15 times with socks. No box. Please feel free to contact me if you have any questions about the fit, size, or condition. I am quite a clean freak, so I think the shoes are in pretty good condition. When wearing climbing shoes, I take the following precautions: - Always wash my feet before climbing - Do not walk around the gym in socks or barefoot - Dry the shoes immediately after climbing with a shoe dryer - Do not climb in the same shoes for more than 2 hours I am also listing other shoes of the same size, so please take a look if you'd like. *To avoid any problems after purchase, please confirm the condition and size of the product in the comments and purchase only if you are satisfied. *I will note any noticeable scratches, etc., in the description, but there may be wrinkles, fraying of the laces, loose threads, minor scratches, and dirt. Please purchase only if you understand this.
