Depending on which market you look at its already the case. Good running shoes are not vought from any of these brands, soccer shoes is mainly adidas/nike and just for fashion there could be a new company every day. Its just branding.
> Good running shoes are not vought from any of these brands
The Nike Vaporfly has made numerous headlines[0] for "technology doping" because runners are using it to win marathons. From the recent NYC marathon, Nike and Adidas dominated in comparison to other shoe brands[1]:
> Of the total 36 podium finishers, 25 were wearing Nike shoes
> Of the 12 winners, 8 were wearing Nike shoes
> Adidas comes second with 6 podium finishers and 2 winners
> Other brands are Brooks (2 podiums), Asics, Saucony and New Balance (1 podium each)

Go to any race. The field is STACKED with people running vaporflys. I see it at our running club. People are suddenly paying their own money to buy the same Nike shoe, when in the past people used kind of whatever they preferred.
Tune in to the olympic marathon trials February 29. I bet the vast majority of the field will be wearing the exact same shoe.
