Now take the ¼ inch bias tape and cut four extra long pieces.  Sew a loop at the end of each that will slide over the ankle strap.
Cut two more long pieces from the ¼ inch bias tape and sew to the tip of the top piece. This will be the toe strap.
You should now have 2 pieces that look like this when put together.
Cut two 2½ inch pieces from the elastic.
Now just sew them to the ends overlapping ¼ on each side of the ankle straps with a zigzag stitch.
You’re almost finished!  Pull the ends through the proper holes like shown.  I tied some loose knots where I thought they should be, tried them on and then adjusted them while it was on the foot. Walk around a bit and make sure it feels right, then tie a double knot.
