Ideally, the toes bear negligible weight while you are standing if your feet have sound posture. When the foot arch collapses, the arch being unable to bear the weight of the body, puts the toes under pressure from the excessive weight they are subjected to. This causes conditions that cause your toes to pain.
When the great toe becomes very stiff or rigid, the condition is called hallux rigidus and when it starts deviating towards the other toes causing its bony joint to protrude towards the outside, it is a case of hallux valgus and bunion. Morton’s toe is a condition in which the second toe is longer than the great toe causing it to hurt. Hammer toes, mallet toes are conditions affecting the second through the fifth toes (mainly second) that depict the formation of various types of curvature in the toes.
While insoles do not correct the toe deformity, they can be designed to offload pressure and provide support to the toe to aid its function.
