I am selling these shoes because I am retiring from climbing. ・I purchased these about 10 years ago. So, I believe they are a model before the P3 system, etc. ・I always wore socks, so I never used them barefoot. ・I don't remember the exact frequency of use, but I mainly used Miura and Solutions, so I only wore these occasionally as a secondary pair. Due to the nature of the product, please understand that these are used items and use them entirely at your own risk. I am not responsible for any injuries that may occur during use.
