It is cool to see how different people's opinions are on how they rank different decades, and even if we agree, we disagree on subtle things like tags or eyelets.
1. I rank early 90's 1st because they were durable enough to be washable, and that was the most nostalgic time period when I grew up and when I saw the most girls wearing them. The 80's fit into that 90's category simply because there were enough from that decade still lying around in the 90's.
2. I rank late-Wolverine Champs 2nd, though I do dislike how many tags there are and the white lettering, which I think is too bold and almost tacky and prefer the lone, blue tag speaking for itself. I don't care if the eyelets are white or silver. I see those as minor aesthetic complaints, though. As for quality, they are best since the 90's and I have not experienced the glue bleeding after washing them that others have complained about. All Keds Champs shrank and lost their shape after the 90's after washing them, but a plus to that is I think it helps break them in.
3. Late 2000's-mid 2010's I rank 3rd. Those were the worst quality in my opinion. With these, the glue actually did bleed for me after washing ones from mid 2010's. The terry cloth lining was unnecessary and made my feet hot and sweaty. The bottom sole would come unglued, rendering the shoe useless. This was a bigger issue during when they got rid of the pebble sole for a short period, which was thin and hard like plastic. If the canvas rips or the foxing comes a bit undone, I'm fine with that. The shoe is still usable, and dare I say gives it a worn personality. But, the bottom sole falling off like this era tended to do is unacceptable. I also hated the seam around the bottom foot bed, which rubbed and irritated my toes.
4. I rank early 2000's as the least favorite due the the flared heel which I felt was uncomfortable as if I was going to land wrong and twist my ankle, and I didn't like the dull, light color of the pebble sole. The quality was still better than the mid-2010's Champs, but since I didn't like how they felt, they rank last.
N/A: I have not tried the Designer Brands version of the women's Champs yet. I've tried the gender neutrals, but I don't consider them to be "original" Champs, so no comment on those, except the appearance is better without the white lettering.
