Answer:
Closed back and sufficient sole.
Explanation:
The foot has the function of supporting and balancing the body on the ground, remaining erect and is also a fundamental part of the locomotion process. The shoe, in turn, must have characteristics that allow, under any circumstances, to really protect the foot, without harming or damaging the foot and providing stability, avoiding slips and falls. To avoid slipping on steps, the shoe must have a closed back and sufficient sole.
