My understanding with Common Projects, is that if you are looking to spend $400 on a blank sneaker, they set the standard and have the most brand awareness, but now there are plenty of smaller brands making virtually identical sneakers with better materials and/or construction for the same price or less.
Like with anything else, buying Common Projects you are paying for the brand (the subtle gold lettering on the side of their shoes).
I got a pair of Common Projects Chelsea boots maybe 10 years ago now. I still have them, they're good shoes. I wore them all the time for the first year I got them. They don't make it into my rotation much now these days though. My most worn shoes now are: Guidi PL2, 11 by BBSxSalomon Bamba 2 high, Rick Owens "Vans", Rick Owens "Dunks", CCP Prosthetic Tornados, and Visvim Christo slides. Everything except the Bamba 2 highs is a replica and cost under $400.
I've heard that Common Projects are pretty good at a $400 retail price point, but it sounds like you got something else.
