Nike's destruction over the past 5 years was really surprised and until I read up about the whole "direct to consumer" fiasco it really helped me understand another trend I was a bit confused about.
About 2-3 years, it felt like, out of nowhere everyone was wearing Hoka and On brand sneakers. In my entire life it felt like the Nike/Adidas duopoly was unbreakable, and then it felt suddenly that Hoka was everywhere.
While Hoka probably executed extremely well, I imagine it was an incredibly lucky position Hoka found themselves in when all those retailers had to replace Nike with something. Maybe even allbirds would be in a better position today had they launched 3-4 years later.
Edit: I just looked it up and it seems both Hoka and On were founded before Allbirds. Seems allbirds imploded (~2021), just as Nike was ceding all their retail space (also around 2021). Had they had another year, maybe they wouldn't have had to pivot into an AI datacenter company.
