They're not way expensive -- $83. (Air Pegasus, which I decided on after extensive research a while ago.)
Just that's enough money that I still avoid spending it if possible.
(Less than $40, eh? Hmm.)
I also read a long article in Slate/ Salon (can never keep them straight, in terms of remembering where I read an article) about the benefits of barefootin', or getting as close to it as possible. That also talked about the dangers of over-cushioning.
Mayo Clinic says new shoes are a good idea though.

The ones I'm wearing are ollllllllllllllld. If I had to guess, I'd say a couple of thousand miles on 'em.
I think I'll go on my previous research but will do a little touch-up just in case... (thanks for the link, ehBeth).
