As you know, concrete is a hard surface that your feet cannot bear to walk upon for a more extended period. Therefore, your feet get hurt often when you are wearing shoes that do not provide enough cushioning, comfort, and support to your shoes. The hardness of concrete exerts a direct impact on your feet's muscles, due to which your feet may become sore and can also damage your sciatica nerves. So, it is highly recommended to wear shoes with good arch support, proper fit, and cushioning for walking on concrete.
