My 13 year son sweats excessive in his feet. same is with my husband. please advise.

Lots of laundry: You have already seen the genetic connection - like father , like son. Some people just have more sweat glands, and this can be specific to certain body areas - like the feet. He needs to be encouraged to change scoks often, monitor for development of athletes foot, wear sandals or flip-flops in warmer weather. Some of the foot powders, especially with aluminum hydroxide, may be helpful.
