How much is too much?

Honestly how much is too much when purchasing shoes?  Sometimes I think that some prices for shoes are way too high.  I mean is there some secret party that goes on when you put your feet in a pair of $3,000 shoes?  Hmmm I am still waiting to discover this theory so in the mean time my limit remains under $100, unless I win the lottery or get a really good job.  I guess the other side of it is you pay for quality, which would also include the different materials used.  If that is the case then I completely understand, but if it is just because of the name/label then its just wrong.  That explains the reason why people purchase knock-offs.
