• a stop disposed on a distal end of the main spring element proximate the lower surface thereof, the stop having a lower surface proximate the lower surface of the main spring element;
• the upper surface of the heel spring element including a heel stop surface on a posterior end thereof and the lower surface of the stop comprising a main stop surface, the main and heel stop surfaces having conforming surfaces when brought into contact with each other,
• wherein the main and heel stop surfaces are operable to move towards each other until they come into contact when walking, the distal end of the heel spring element flexing more than an end proximate a mid-portion of the base body;
