Excellent condition slip-on shoes from BOGS. Dark blue and waterproof. These do not have a size on them that I can find -- they measure exactly 9 inches long, which I believe is a 4.5. One shoe does have some staining inside the heel (see photo). Otherwise these are in great shape. Measurements are approximate.Actual color may vary from what is displayed on your screen, due to resolution and lighting.Pet-friendly, smoke-free home.S-1
