Claw toes, or hammer toes, is a condition where the toes cock up. Initially claw toes are seen during walking due to muscle imbalance. Later, this condition becomes rigid and the toes stay cocked.
Claw toes cause irritation to the top of the toes as they rub against the shoe.
This condition also makes it difficult to find shoes that fit properly. In addition to these three deformities, painful calluses often develop on the bottoms of the feet and the feet become somewhat rigid. The progressive nature of CMT makes early assessment and long-term treatment planning prudent. A careful evaluation of the foot is the first step. Distinguishing between fixed and flexible components of each deformity is essential to the proper management of CMT and formulation of an individualized treatment plan.
