"It's between a shoe and a sock"
Sadie is dressing her little darling when she tosses aside, out of frustration, his baby shoes and socks. The shoes are too stiff for its tender feet and the socks don't stay on. She decides to put these hand knit moccasins on him. She discovers they are a cross between a shoe and a sock. These moccasins stay on like a shoe and they have the comfort/coziness of a sock.
