The Fibonacci Fit

How do they FIT?

NOTE: If you are between sizes round up a half size!

LENGTH & WIDTH - Our shoes have a slightly narrower fit when compared to a sneaker. The shoes fit to size as measured with a Brannock Device® (standard foot measuring tool). We currently only offer a REGULAR "Dwidth and do not offer a wide. We recommend to order a half size larger if you tend to have a larger foot. If you have even needed a wide shoe then these maybe too narrow for you. We hope to bring a wide size in the future.

TIGHTNESS - Our shoes are linned with FULL GRAIN LEATHER and can feel a bit snug at first. This high quality leather will stretch and form to your foot over time. You will want to treat your shoes with a leather conditioner to keep them nourished, soft and flexible! In addition: Our sport insoles are thick and can be replaced with a thinner option to create more foot room.

COMPETITOR - The closest match to size, fit and feel would be the ZeroGrand series from Cole Haan.

The Fibonacci Difference

Our shoes were created for both formal and casual wear. Fibonacci has infused superior quality materials with state-of-the-art technology, ensuring all day comfort and long-lasting endurance. Bringing together design, quality, and comfort.

All our shoes come with the following features: Temperature regulating material, high-performance sport insoles, flexible custom outsoles, a premium leather Interior, a suede heal cup, high end wax laces and a high-quality metal shoe horn.

The Liber
Our Unique Comfort

1) The temperature regulating material keeps the foot cool in the summer and warm in the winter and provides cushion that hugs the foot like a sneaker.

2) The high-performance sport insole and the added silicone gel layer provide a level of impact control above all others.

3) The padded collar, suede heel cup plus the stitch and turn seams add an extra level of comfort which helps protect the heel from unwanted rubbing.

Thermal Tech
Infused NASA Technology

We are using a special material that was designed and certified by NASA to be used in their spacesuits. The thermo-technology was originally used in space gloves for protection from temperature fluctuations in space!
