Five Decades of
Footwear Excellence.
From a family basement in the Treviso district to a European leader in technical footwear manufacturing — the O-three story spans five decades of craft, innovation, and industrial scale.
Five Decades of Manufacturing Excellence
The Beginning
The Vendramini family begins crafting footwear in the basement of their home in the Treviso district. What starts as a craft operation becomes the foundation of decades of technical expertise.
O-three is Born
Drawing on over thirty years of family manufacturing knowledge, O-three S.r.l. is formally established in Altivole, Treviso. The company inherits the Vendramini family's technical rigour and industrial ambition.
European Leadership
O-three grows into a European leader in ski boot production. The decade's defining achievement: the development and industrial application of a patented closure technology for snowboard boots, a technical innovation subsequently licensed by a major international client.
New Leadership
A new generation of leadership takes the helm, bringing renewed direction to the company. O-three accelerates its international expansion, strengthens its private label offer, and consolidates production capacity in Albania.
Industrial Scale
With production facilities in Albania delivering 30,000+ pairs per month, O-three operates as a structured industrial manufacturing partner for global brands across trekking, safety, motorsport, and winter footwear categories.
