Thanks for giving this insight and providing this many links!

I found this font while doing an unrelated project and it made me think of the allbirds font - so I said to myself "huh, I wonder if it's the same...?" So I looked it up just in case I was right and I could get a free ego boost. I don't think it's the same, but google suggested this thread and based on the prior response, I'm not sure if you found a suitable match, so I figured I'd offer this, even if it's a few years late
