In
toeing - off (along with proper heel - strike), you are able to use the full range of motion in the ankle and foot which helps to keep those
joints functioning well and prevent breakdown and degeneration.
This tightening of the plantar fascia has two
functions; (1) the medial arch of the foot is packed tighter and is increased in height, allowing for improved loading capacity and shock absorption, and (2) the foot becomes more rigid and has improved
function as a propulsive lever (Figures 2 and 3).10 Consequently, if during the swing phase the
toes are trying to «grip» the flip - flop, the 1st MTP
joint is not able to extend and the windlass mechanism of the foot is compromised.
