My dude, it's unfair to complain about sole separation issues on a sneaker that's over a decade old. The sole separation you're experiencing can happen as the glue gets brittle over time and you can easily remedy the situation by re-glueing it. Big ticket items like automobiles and homes would need minor/major repairs after 10 years of ownership if you want to put things in perspective. That said, were you satisfied with the quality of the shoes when you purchased them in 2002?
I have to ask, as the complaints for the past 6 years pertain to overuse of synthetic materials, stripping away of sockliners/padding and crummy paintjobs/midsoles on NEW or 'just released' shoes. How can you fix cheap pleather or midsoles that crack after one wear?
