Vinegar is acid, so at least it won’t make your feet alkaline.

But getting advice on medical matters from the internet is a bad idea. If you have any type of infection that is bad enough to seek advice for it, you should seek advice from professionals who have training and experience in dealing with such things.

Then I just started washing my feet during showers, in a similar way as washing my hands after using the toilet. Soap and warm shower water, using my hands to get to all the surfaces of the feet, and getting my soapy fingers in between my toes.

Itch gone, has not come back. I don’t recall how long it took to work, but I’d say a month would probably not be excessive either way. Washing my feet became routine, and no more itchy feet.

Really: before going off to the wild blue yonder in search of remedies, start with the basics: soap and water and gentle scrubbing, every time you shower. Dry your feet with a towel and let them air dry before putting socks on. If expecting hot sweaty weather, put a little baby powder in your socks to help keep your feet dry.

Fast showers are cutting corners. Take the time to wash every square inch of your body. This takes about 15 minutes including washing your hair. Starting with basic cleanliness gives your body’s normal microbial ecosystem the best basis to behave normally.

The place to conserve water isn’t on basic sanitation including personal hygiene, it’s on needless frills such as lawns in desert climates such as California. But as for water conservation, I recycle my graywater from the laundry, to use for flushing the toilet, and that saves about 20% on total indoor water consumption. Thus no need to skimp on laundry or on toilet flushes either.

All of this stuff is convergent. Good hygiene, good sanitation, and good conservation, all work together.
