[0008] Furthermore, marking blocks for pre-positioning the second foam are arranged around the leather surface layer.
[0009] Furthermore, the first foam and the second foam are both made of polyurethane foam material.
[0010] Furthermore, the positions of the first micropores and the second micropores are staggered with each other.
