This discussion really annoys me when it comes up. As weegie stated pages back, that no one even acknowledged, she has a medical condition that warrants a shoes on approach. I too, have a neurological condition that makes walking without footwear extremely painful. My neurologist, GP and podiatrist have all advised me to wear my footwear as much as possible. Clearly I do not sleep in it! Because I have significantly reduced sensation in my lower limbs and feet my footwear provides protection from damage that could lead to serious infection. I have orthotics expensively created by the NHS to help with walking and balance - I am much more likely to fall over without footwear. I have in the past developed a serious foot infection due to stubbing my toe (en route from bed to bathroom) and not realising the damage due to the neuropathy. A worst case scenario is that this could lead to amputation - no joke.
The only positive of this debilitating condition is that I cannot wear any type of heeled/fashion shoe, as am forced by necessity to wear sturdy walking shoes that can accommodate my orthotics, so my feet cannot be ruined any further!
You know, I do respect everyone's right to do want they want on this issue in their own homes. However you have no idea what it is like to have to explain to someone why I need to keep my shoes on. I used to embarrassingly give to much info. Now short and sweet I just say "I have a medical condition that necessitates me wearing shoes". No one has barred me from their house . . . .yet! And thankfully I move in circles where this is a rare request.
I don't live in a rental or down a muddy lane.
I just think, there is no good reason to put someone in this potentially awkward position.
Walk a mile in someone else's shoes. Pun intended!
