Which of the following is a component of an effective foot care program to prevent calluses?

Applying emollients to prevent friction is a critical component of an effective foot care program aimed at preventing calluses. Emollients help to maintain skin hydration and elasticity, which reduces the friction that can lead to the formation of calluses. By softening the skin, emollients minimize the chances of rough, hardened patches developing in response to excessive pressure or friction from footwear or activities.

In contrast, wearing high heels regularly can increase pressure on certain areas of the feet, potentially leading to callus formation rather than preventing it. Neglecting regular foot hygiene can contribute to various foot problems, including calluses, as it allows dead skin to accumulate without removal. Wearing tight shoes can also exacerbate friction and pressure on the feet, making calluses more likely to form rather than helping to prevent them. Therefore, the use of emollients stands out as a proactive measure in foot care.
