Is a foot grinder useful for grinding calluses?

Foot grinders are generally useful, and some remove calluses or dead skin. Most calluses are caused by long-term walking or standing in shoes that are not suitable for local friction. You can usually use hot water to soak your feet. Soaking your feet in hot water can soften them, and then use angle grinders to soften them. If it is removed by grinding, you can get a good improvement effect. However, you must take the correct method when using it. Improper operation may have a certain impact on the skin. If necessary, it can also be treated with acid brushing or fruit acid peeling. During the treatment period, be sure to rest more, avoid overexertion, and do not stand or walk for long periods of time.
