> It doesn't explain why every couple of years I have another four or six pairs of yet another set of socks, from the same company, but with enough variation that now I have multiple different generations of CK socks that aren't pairable.Most sock brands don't actually produce socks, they license the brand name out to third-party textile manufacturers to make the product.
They'll often switch partnerships to new manufacturers which has a drastic impact on the produced product in terms of materials, feel, overall quality, etc.
In many cases they even license the brand out to multiple manufacturers simultaneously, using different manufacturers for higher end stores than cheaper department stores, so even in the same time period you could get very different socks of the same style from the same brand depending upon where you buy them.
Same core problem as typical cost-cutting enshittification -- everything is hyper-optimized to extract the maximum amount of value at the expense of every other consideration.
