Why does flatfoot occur and why is it so dangerous? Numerous reasons for this widespread problem (hence its prevalence): - overweight; - peculiarities of daily reality; - wearing anatomically "harmful" shoes (wrong size, low quality, etc.); - familial predisposition. Those are just the main causes☝🏻 But why is flat feet considered a serious pathology - what is critical to the body in a flat foot? Well, it's a kind of shock absorber for our whole body. Healthy people have a high arch of the foot that allows the legs to easily carry heavy loads - it "springs". But with flat feet, the arch decreases and this function is suppressed. Therefore, this pathology leads to problems in the lower leg, knee, hip and even lower spine.
