I mean, as I said in the original comment, I think it’s most likely that Dow never received the sneakers at all; it seems entirely plausible to me that the resaleable-looking shoes were being diverted and exported by the contractors who had been hired to collect the sneakers from the donation bins. (and I’m not 100% certain that I have a problem with that, for “reuse is better than recycling” reasons also discussed elsewhere in these comments, but I can see how Dow might be displeased with it if it was a contractual violation)

But that doesn’t change the fact that stuff which is going to be shredded always goes through a validation process first and — unless the process failed for some reason — those shoes were never going to reach the grinders and were never going to end up in paths/pavings, even if they did get to Dow.
