About COS
COS is a Swedish fashion brand founded in 2007, known for minimalist Scandinavian design and contemporary style. The footwear collection includes trainers, boots, and refined casual shoes with clean aesthetics.
How Does COS Fit?
COS shoes typically fit true to size, but their trainers have a narrow shape. The brand uses European sizing, with sizes typically ranging from 35 to 42 for women and 39 to 46 for men.
Sizing Advice
For COS footwear, order your normal EU size. If you have wider feet or are between sizes, consider sizing up for comfort. Sock thickness also matters - finely woven cotton allows your normal size, while thicker socks may need more room.
Width & Fit Characteristics
COS shoes can be narrow or wide fitting depending on the style. The trainers particularly tend to have a narrower fit, so consider your foot width when ordering.
Popular Models
COS is known for their minimalist leather and suede trainers, Chelsea boots, and contemporary sneaker designs that blend fashion with functionality.
