How to Measure Your Foot for Our Slippers: If you are unsure which shoe size to purchase, please follow these steps: •Draw a straight line longer than your foot on a piece of paper. •Place the paper on a flat surface and stand on the line with your heel and longest toe centered. •Place a mark on the line at the tip of the longest toe and at the back of the heel. •Repeat the above steps for your other foot. •Measure the distance between the marks. Taking the larger of the two measurements, use the chart below to find your correct shoe size.   Tips:   •Because the foot is three-dimensional, a two-dimensional measuring tool such as a ruler or Brannock device can only approximate your true shoe size. •Make sure you are standing and wearing the socks or stockings you will wear with your new shoes. * Made of 80% cotton and 20% polyester to warm your feet in cold weather. * High quality black synthetic foam sole for comfort and non-slip safety. * Sublimation printing ensures bright colors and will not fade easily after washing.
