I purchased these a few years ago. The size is 35. The upper is a combination of deer (deer leather) and calf (calfskin). Soft deer leather is used for the front half and body for a gentler feel against the foot, while more durable cowhide is used for the back half, heel area, and straps to enhance the hold. The fit is roomy. The Velcro strap on the instep also provides a secure hold. *The last photo is borrowed. It's a wearing example.*
