What does the term fallen arches mean?

The term 'fallen arches' refers to a condition called pes planus or flat feet. It describes a foot structure where the arch has either not developed or has collapsed, causing the entire sole of the foot to touch the ground when standing. Normally, there is a natural arch in the middle of the foot that helps distribute weight and absorb shock during walking or running. When this arch flattens or collapses, it can lead to issues with stability, balance, and foot pain. Fallen arches can occur due to various factors, including genetics, age-related changes, injury, obesity, or certain medical conditions.
