I'm looking for an antonym of the word spoiled.
The sense of spoiled I have in mind is a positive one: "I've become spoiled by these comfy shoes."
I'm looking for a word or short phrase to say: "I've become antispoiled by these horrible shoes and now any other pair would be comfortable."
The closest phrase that I'm aware of is to have one's standards lowered, which isn't quite the same thing and certainly isn't very pithy.
