Running shoes with good arch support are designed to provide stability and comfort for runners who need additional support for their feet. They are often recommended for people with flat feet or high arches, as well as for runners who experience pain or discomfort in their feet, ankles, or knees.
The arch of the foot is a complex structure of bones, ligaments, and muscles that helps to distribute weight and absorb shock when walking or running. Good arch support can help to prevent the arch from collapsing, which can lead to pain and discomfort. Running shoes with good arch support can also help to improve stability and balance, and reduce the risk of injuries.
