An Innovative Measuring Tool
The Original Sock Ruler measures adult sizes and a child's size large. Made from a durable plastic that is flexible and provides easy to read measurement markings. Using a traditional tape measure, measurements can be inaccurate as the fabric is stretched to lie flat. With the Sock Ruler, the fabric lies flat because the ruler is placed inside the sock for accurate measurement. Please keep in mind that this ruler does not actually measure the foot's actual length. Instead, it provides measurement markings for when you should start the heel turn and toe decreases.
