(Dons hard hat for posting about slippers on S&B) 
I wear flattish shoes with good soles due to previous joint issues. At home I have solid floors and walking barefoot / in socks is not comfortable. I tried Totes slippers that were touted as good supportive soles etc but they collapsed within a month, no better than cheap supermarket slippers and probably worse. After popping old leather sandals in the washing machine (yes, yes) and wearing them at home to check they're still ok, I thought maybe keeping a pair of outdoor quality shoes or sandals for indoor wear may be an option... If anyone else who wears "good soles" has any ideas I'd like to hear!
