COS
True to SizeCOS fits true to size in flats and casual styles but uses a slim, minimalist last that runs narrow in dress shoes and boots. The leather sneakers, loafers, and chunky boots all wear your normal EU size for standard feet. Wider feet may want to size up half a size in pointed-toe and dress styles. The build quality is high but the fit is unforgiving for wide feet.
COS is generally true to size. Order your usual size.
