Theresia Derby Oyster Black

$650

The Theresia Derby is an elegant silhouette which draws inspiration from bygone centuries. The upper is crafted from a single piece of horse hide that shows very slight irregularities, adding to the depth of its appearance. The upper sits atop a leather frame sole and outsole that is stitched with a Blake-stitch construction. The shoe is made in Portugal.

All leathers are natural, which means that they age over time—developing beautiful patina and molding to your foot. This natural process gives each pair a unique character. To ensure that your Sine & Cosine shoes age as beautifully as possible, there are a few care-taking steps you can take. 

When dirty, use a damp cloth to gently brush away the dirt from the shoe. For more delicate materials, like suede, we recommend using a soft brush or a suede eraser. 

Regularly treat your shoes with the right spray, conditioner, or polish to keep the leather in its best condition. Your local cobbler will help you find the suited products.
