The Portsea mens boat shoe is a nautical-inspired footwear style that is primarily associated with several premium Australian and European lifestyle brands. Many prominent versions of the 'Portsea' shoe, such as those under the Henry Sartorial or Henry Bucks labels, are designed in Australia and handcrafted in Tuscany, Italy, using high-quality materials like deerskin and calfskin. The brand name 'Portsea' is frequently used as a model name for footwear intended for the upscale Australian coastal market, referencing the exclusive seaside town of Portsea on the Mornington Peninsula.

While some specific models are produced in Italy, other footwear lines using the Portsea name, such as those by S. Kidman or general promotional apparel, may be manufactured in various locations including China or Portugal. Historically, boat shoes (or deck shoes) were invented in the United States by Paul Sperry in 1935, but the Portsea design represents a localized adaptation for the Australian luxury market. Ownership typically resides with independent retail groups or boutique menswear companies rather than a single global conglomerate.
