I have thought about loafers. That prevents puncture between the ball of the foot and the heel, and has a solid rubber area, extending over the heel. With soft foam rubber under the ball of the foot, for both flexing and grip, for quick movement. This heel and behind the ball form to the foot, for comfortable support. While the ball of the foot, flexes beneath, with grooves for assisting the flexing of the sole in this area.

A breathable mesh is over the top of the foot, to reduce sunburn while allowing abundant ventilation. Along with elastic material holding the flap above the foot down, so the loafer doesn't fall off. A protective rubber top on the end of the loafer keeps the toe from the discomfort of bumping into things. And the low slope heel for ground impact absorption. 

This age reversal facilitating high visibility orange with high visibility yellow, will indicate, the need to not be elderly. Instead, the potential of either young adult or adolescent area can be had, as a possibility, unless I am to be perceived as elderly conduct. A non-elderly person's style of loafer needs to be had by me, for age reversal to a young adult as a potential.
