Cheaney's Kenegon, Size is UK6.0-F. I purchased these used and don't have the box, so this is just a guess, but based on the softness of the leather and the color (not burgundy or almond), I believe it's mahogany pull-up grain leather. It's softer than the standard grain leather Kenegon. *This is just a guess. Please do your own research. Thank you for your understanding. Below is the description of pull-up leather from the website: The upper uses pull-up grain leather (cowhide) that has been treated with oil during the tanning process. Compared to conventional grain leather, it has a more natural grain, is highly water-resistant, and is tough, making it resistant to scratches and stains. It has the rich gradation of color unique to pull-up leather, and you can enjoy a beautiful aging process as you use it.

The soles are in good condition, so they may have been resoled once. After purchase, I washed them thoroughly with saddle soap and have maintained them. Thank you very much!
