I usually ignore these kind of threads because they tend to devolve into arguments over why you should support "x company", but I'm bored at work so fuck it. Let's play along.
Footwear: adidas , I know I'll catch some flack for that one, but it's not that I dislike their product at all. Their shoes are just not designed for someone with wider, flatter feet such as myself. The only pair I never experienced pain while just simply wearing them. Still love their team and will daydream about being able to wear their shoes.
Clothing: Supreme Not much else needs to be said. Overpriced, overrated, too much "I'm better than you because I conflate my value in this world with the amount of money I spent on these outfits."
Bloards: too many to name, but to pinpoint just one... I'd have to say FA/Hockey. I know it's trendy to hate on these companies, but my complaint is that their bloards are just meh. Broke on on a flat ground pop shuv last summer and will absolutely never purchase another.
Trucks: Tensors They just look like cheaply made toy trucks for completes you'd buy a 5 year-old at Walmart or some shit.
Wheels: Ricta Saw a dude split one of those Ricta Cloud wheels straight down the middle after landing a flyout when he weighed MAYBE 110lbs. This was like 10 years ago, but my opinion still stands.
