What is another word for sunken arch?
Pronunciation: [sˈʌŋkən ˈɑːt͡ʃ] (IPA) 
The term "sunken arch" refers to a deformity in the foot where the arch collapses and comes in contact with the ground. This condition is also known by other names, such as flat feet, fallen arches, or pes planus. The use of these synonyms depends on the severity and cause of the condition. Flat feet are generally a result of genetics or repetitive stress on the feet from activities like running or standing for extended periods of time. While fallen arches may be due to injuries or underlying medical conditions like arthritis or obesity. Regardless of the cause, the symptoms of sunken arches can be alleviated through orthotic inserts, proper footwear, and exercises that strengthen the feet.
