It seems like from 1996-2006 running shoe prices didn't really increase that much, maybe $1 a year. But in the last 2 or 3 years shoes have increase more like $5 a year. I'm just basing this on a mid-level trainer like an Adrenaline or 2140 that used to be $80/85, rose to $90/95, and is now $100/105.
Am I just imagining this sudden increase because it was too long ago and I was too young, or does anybody else notice this trend?
