I think, for the most part, shoes can take quite a bit of abuse. I live in the UK where it rains a lot and I see women wearing all types of shoes in the rain. I am a bit more "careful" than that though and don't wear expensive shoes or shoes I really really like in those conditions. However, I don't work so there is no need for me to leave the house when it's pissing it down. However, there are shoes, well more like materials, that are a no non in the rain; Suede comes to mind.
As for the wear and tear that comes from walking on the pavement, it breaks my heart to see the soles and heel tips mangled but that is just the nature of the beast.
