SINE & COSINE is a thesis on luxury footwear. 

Amsterdam-based luxury footwear brand SINE & COSINE finds itself at the crossroads of academia and design, merging mathematical clarity with historical inspiration. Founded in 2021 by two mathematicians with no formal education in fashion, the brand developed a unique perspective on luxury design. This perspective is enhanced by a historian who joined the brand. 

Rooted in a multidisciplinary foundation, SINE & COSINE crafts minimalist, contemporary footwear by reinterpreting historical references through an academic and mathematical lens. Much like mathematicians distill complex problems to their essential components, the brand analyzes the defining elements of classic designs with precision and clarity. Each detail is carefully evaluated—embraced for its timelessness or refined to align with modern sensibilities.

At the heart of SINE & COSINE’s vision is a commitment to thoughtful exploration and creative expression. Their definition of luxury goes beyond aesthetics and relevance, embracing practicality and craftsmanship in every step of the design process.
