Hi Cerinthe! Welcome to DF!
Your question is not weird at all. In fact, DF is full of helpful advice on that topic. If you type the words “cleaning shoes” into the Search box at the top right of the screen, you’ll get links to previous threads on the subject:
That said, it looks like the most recent thread about shoe cleaning (before yours, that is) was more than 7 years ago. This makes it likely that there are a bunch of new DFers who have joined since then, and maybe new products on the market, so it’s good to bump (renew) this topic discussion and get updated recommendations.
I don’t remember any threads about how to clean the inside shoebed where it contacts the sole of your foot. I’ve wondered that myself (though not very often, because it doesn’t show when I’m wearing my shoes). I think the answers will depend on what materials your shoes are made of, both inside and outside. My initial thought, without knowing anything about your shoes, is that baby wipes for sensitive skin, such as
these, are a good place to start - as long as you don’t rub too hard or saturate the inside of the shoe. It’s entirely possible that you can throw the shoes into a sink or tub full of soapy water, or the washing machine (inside a zipped pillowcase - I’ve done this with my kids’ Converse high tops), or even the dishwasher (my hubby does that with his baseball caps) - but I advise that you NOT try any of these until/unless you are confident that the shoes won’t be damaged by those methods.
(FWIW…my preferred alternative to cleaning shoes is simply to wash my feet after I’ve been walking around [usually barefoot] in the back yard. Standing on one foot while washing the other [in the sink or tub or shower] is a great way to practice balance, lol.)
