Which method can help prevent callus formation?

Soaking feet and using callus files to reduce thickness is an effective method for preventing callus formation. Calluses develop as a protective response to repeated friction and pressure on the skin, often due to ill-fitting shoes or excessive activity. By soaking the feet, you soften the skin, which makes it easier to manage and remove any existing calluses without causing damage. The use of callus files allows for targeted reduction of thickened skin, helping to maintain smoother, healthier foot surfaces. Regular care of the feet through soaking and proper filing can help to minimize the buildup of dead skin cells and reduce the risk of painful callus development in the first place.

Wearing sandals in all situations may not provide the necessary protection or support for the feet, which could lead to more friction and potential callus formation. Only wearing shoes at home doesn't address the need for proper foot care in more demanding situations, while ignoring foot care altogether would certainly allow calluses to form and worsen over time. Thus, the approach of soaking and filing is proactive and preventive, targeting the root cause of callus development.
