It seems that the modern shoe manufacturing giants have mastered the shady art of Planned obsolescence...

I grew up in the 80ties...the greatest era for shoe design apparently.
Clearly stitched one piece soles are largely a thing of the past having been largely replaced by a series of glued together pieces destined and designed to fail long before the shoe should wear out if they had kept the superior designs of the 80ties.
Adidias were always my favorite make and my sambas and superstars lasted 5 or six years of hard wear without fail.
I bought 2 pair of Adidas ilation 2 from Academy Sports and wore them exclusively at work where I basically I am walking all day indoors... I didn't wear them for one minute of stressful athletic activity and both pairs failed in the exact same place in the exact same time.
I sent them back to Adidas as Academy Sports rebuffed me immediately even though two pairs of shoes had both failed in under 5 months total.
That's 10 weeks of wear of indoor walking exclusively per pair.
Adidas offered me a generous coupon to their website exclusively where I had a hard time finding my size.
After a week or so I finally was able to replace the two pairs of junk Adidas I bought previously but I've noticed all of them have glue together multi-part soles.
Unless you buy the Retro models that are exorbitantly expensive you cannot find a one-piece stitched on sole easily.
I fit best in a size 12 4E shoe.
I noticed New Balance seem to fit me best.
Having an unusual size foot is difficult enough but with the junk construction of the modern glue shoe is becoming more and more difficult to get a decent pair of shoes without spending a king's Ransom
It's 2019 for God's sake, our manufacturers are treating us like fools and selling us inferior products at exorbitant prices knowing the primary customer base is most likely spoiled privileged fickle youth who will throw out a perfectly fine pair of shoes because one portion became unglued.
I have a science degree and work in public safety and science so I understand chemical welding and modern manufacturing process is better than the average person.
I know it's perfectly possible to put together a chemically welded multi-piece sole that is reliable but I don't think that's what they're doing in the majority of manufacturing activity.
