I’ve got some ankle-high suede house slippers with a plush lining, the kind that keep cold feet at bay in winter. Not the now super-expensive kind that still have the wool, the kind that have plush instead. IOW, ~$50 shoes (or more, depending on where you buy them). On top of that, I paid $60 to have a lift sole attached to the one, because thanks to a hip & knee replacement on one leg, there is now a 1¼ inch difference between the relative lengths of my legs, compared to what they were before the surgeries. The cheaper alternative would have been to insert a lift, as I do with some of my shoes, but that would have negated the benefits of the plush on half the sole of one foot - not what I had in mind. They’re only two years old. Slippers of this kind are well-made, and have lasted me for 7 or 8 years in the past.
Last summer, my son started going barefoot in my apartment, and I didn’t even think about the possible consequences. He’s got a permanent fungal infection on his feet - which he shared with me via the bare feet on my carpeting. It’s starting to be warm house slippers weather again, but if I use those slippers, I’ll reinfect my own feet. The prescription antifungal cream isn’t very effective for me, and the oral med that does clear up the infection is really, really hard on the liver. Neither the doctor nor I want me to have to take it repeated times.
I’m on Social Security, so this is a substantial investment for me. I really can’t afford to throw them out. How can I disinfect the inside of those slippers, without destroying the plush?
