Sturdy vintage black men's cowboy boots! I don't see a brand here. Acme maybe? Stamped in the inside is "Genuine Leather Foot" and "Balance Man Made Material".  The leather and faux leather is thick and has a shine to it. There's some creasing, a crack above the right ankle, cracking and some separation of the lining, and some wear on the soles, all shown. These are still in great shape with a lot of life left! Marked a 10 1/2D, please check measurements carefully, as I don't do sizing returns. Widest part at ball of foot measures 3 3/4", length along insole to toe tip is 10 3/4"-11". Shaft is 11 3/4" from bottom of upper at back of foot, upper is 7" flat across top at calf.
