How much is too much? Shoe edition

Elizabeth's post below and Karen's response made me wonder how much most women are willing to pay for shoes. I covet the Miu Miu patent leather boots shown above, but with a price tag of $700+, it just ain't happening.
I did splurge once on a pair of high-heeled silver sandals that were about $200. I wore them to nearly every wedding and dressy event for more than a year, receiving compliments on them each time. So they were well worth the price. But that was an exception; I generally try to keep footwear in the under $100 range (mainly because I buy so many pairs).
How about you? How much would you spend on a pair of shoes?
