Thank you for viewing! This is a work boot from Clarks. The inside of the boots is lined with Gore-Tex, making them waterproof and breathable. I've only worn them a few times (please see the photos of the soles for reference), so I think they're in good condition. I've stopped wearing anything other than sneakers, so I'm releasing these at a good price. Please give them a try. Thank you very much. Regarding the size, it's 25cm, but as is often the case with Clarks, they run a bit large. For reference, I usually wear a 26cm in New Balance. Please use this as a guide.
