The calfskin upper of this loafer is specially treated to create a rich deerskin effect grain, giving it a luxurious appearance and comfortable fit. This style, first patented in 1963, features a dotted rubber sole inlaid onto the base for maximum flexibility and is handcrafted using the exclusive "cucita su forma" (sewn on the last) construction method, which involves 800 steps per pair to complete. The meticulous attention to detail, from the eyelets to the smooth apron-toe seam, reflects the brand's historical heritage.
