The Foot-Up inlay is the replacement piece that fits underneath the laces of the shoe and attaches to the black ankle cuff by way of a strong black elastic strap.  Over time the strap stretches out and looses its effectiveness with pulling the foot upward into dorsiflexion.  This motion is required to help the foot clear the floor with the swing through phase of walking. 

One size fits all
