I have loved to see women wearing Keds Champions especially without socks ever since my youth.The company has been around for a while and I'm sure has produced them with many color/pattern and with slight design differences.Has anyone bothered to archive all of this in one place on the web?Is there at least a time line showing the variety of construction differences by year/decade (i.e. sole thickness,toe shape,heel type as with the infamous wedge of a few years back)?
