Color will vary slightly from photo. Honestly I cannot tell if they are dark navy blue or black. They were worn with black scrub pants but look navy blue in some light. Size chart is from Dansko website. Size 37 is approximately size 6.5 to 7 in women’s. Please see photos for condition of soles, minor Scuff marks and scratches. Smoke free home, my dog doesn’t wear my shoes 😃. Reasonable offers welcome
