Hirasawa , et al. | April 24, 1973 |
A rigid member is placed above the sole of an infant's shoe, and extends across the heel and to the base of the fifth toe to provide support over the full heel width and forward along the outer edge of the foot outline. The effective width of the infant's foot is thus increased to permit more stable standing and walking by the infant.
