To not be worried that my feet smell of vinegar

[raranah]

Any scientists that can confirm this is normal? Im planning on just boil washing my slippers and then scrubbing feet, washing with soap and drying with hairdrier.

Gross. Best wash them straight away. Trust me, I'm a scientist.

Mine often do.

Throw away the slippers.

I find when footwear has gone that bad it comes back

I reckon I'd chuck the slippers. Why on earth do you need to dry your feet with a hairdrier? Just use a clear towel.
