The Puma Usan Snake style combines inspiration from classic dress shoe uppers and sprint racing soles with UNI construction to create an environmentally friendly and durable shoe. UNI construction is Puma's cross category footwear design technique in which the upper is stitched, rather than glued, lasted or nailed to the sole of the shoe eliminating the external midsole. This version of the Usan features a clear sole with Cat logo. UPPER Combination of snake like leather and synthetic leather MIDSOLE Internal EVA midsole OUTSOLE Carbon rubber
