Vintage Texas Brand Western cowgirl boots

Vintage Texas Brand cowgirl boots. I am not sure if there are different kinds of leather for the shoe part and the leg parts??? Or just leg part was worn-out??? Many wrinkles and lighter black. But, not any of the leather is ripping off. Size 5 1/2. Seems in good condition. I am size women 7 - 7 1/2 and fit well. May be men’s 5 1/2 size. please do not hesitate to ask any questions.
