The arch of my foot hurts when doing skipping ropes. i'm doing this for some simple exercise. is that bad?

Arch pain: Many people suffer from flattening of the arches when they stand up (flexible flat foot). This changes the position of the tendons and joints in the foot, causing muscular imbalance and sometimes even arthritic changes. It can also put stress on ligaments, such as the plantar fascia, which runs across the bottom of your feet and supports your arch. Visit your podiatrist if it does not go away.
