If you send the elderly, you must first prevent them from slipping. Your legs and feet are not good. If your shoes don't slip, you will fall down more easily. Then most old people will bend over and their joints are fragile, so choose shoes that protect joints and correct gait. I saw a smart walking shoe on crowdfunding in JD.COM yesterday, and it felt good. It is not only a voice prompt, but also a scientific position. I bought two pairs, you can refer to them!
