Paco Boot in Buffalo Black
Description
The upper of Sine & Cosine's Paco Boot is a single piece of Italian buffalo calf leather, so it carries no stitching, just a pointed toe and a rear YKK zip. In Buffalo Black, it stands on an exaggerated high Cuban heel in leather. Blake-stitched to a leather frame sole, lined in soft cow leather and fitted with a cushioned insole, it is a deliberately minimal boot where the heel does most of the talking.
