Hard skin on the inside of the sole, is it due to the knees? The cause varies depending on the location

Even by the location of the calluses on the sole of the foot

I can identify the disease~

I need to check the calluses on the sole of my foot haha

Learn about the causes of different types of calluses on the soles of the feet.

Callus on the inside or outside

A hard callus on the sole of the foot can cause pain with each step. However, if there is a callus on the inside or outside of the sole, it may indicate an imbalance in the hip or knee joints. When the joints are misaligned, the foot may twist sideways or bend inward while walking, causing uneven weight distribution. If gait is not corrected, it can lead to excessive wear on specific areas of the knee joint, increasing the risk of arthritis.

Callus that has developed on only one foot

If calluses are only present on one foot, scoliosis should be suspected. Scoliosis refers to a condition where the spine does not maintain a normal shape but instead curves or twists. Because individuals with scoliosis cannot evenly distribute their weight on both feet while walking, calluses may develop on only one foot. If scoliosis is not treated promptly, it can lead to back pain, leg numbness, and in adolescents, growth problems.

Callus embedded on the second toe

If a callus forms below the second toe, you should be cautious of hallux valgus. Hallux valgus is a condition where the big toe bends toward the second toe. When this happens, weight is not evenly distributed on the sole but shifts toward the front second toe, causing a callus to develop in that area. Calluses can also form on this part when wearing high-heeled shoes with high heels.

Callus under the little toe and big toe

In cases of high-arched pes cavus, this phenomenon occurs. This is because individuals with pes cavus often walk with their heel, little toe, and big toe touching the ground. Conversely, people with a short Achilles tendon, such as those who walk on tiptoes, develop calluses under the second, third, and fourth toes. This is due to the forward shift of body weight.
