Fibonacci shoes are made with the highest quality materials for durability and longer lasting wear. Our men's chukka boots are built with premium suede and our men's derby dress shoes are made with full-grain leather; the full-grain leather is topped off with a beautiful hand polished finish.

Our interiors are built for all day comfort; they fit and function just like luxury sneakers. Both the Liber and Abbaci are constructed with calfskin leather, a suede heel cup, a sport insole, temperature regulating material and an added specialty layer of silicone gel for cushioning. Your feet will feel cool and comfortable all year round.

Both our midsoles and outsoles are custom designed. Our midsoles are flexible, lightweight and thin, which provides a more professional appearance over "luxury sneakers". Our outsoles have a unique tread pattern for stability and use a reinforced carbon composite rubber to ensure longer lasting wear.
