Couple that with the fact almost everyone seems to run now, and that running shoes/trainers have become acceptable fashion in all but the haughtiest of occasions.
In the 90s, running wasn't even really a thing. A few people went "jogging" for exercise. Otherwise it was a proper sport in which very few partook. Trainers were predominantly worn by children. Adults wore "real" shoes.
Something changed in the past ten years or so. I feel like Nike kept the childish association whereas brands like Hoka became acceptable for adults to wear.
