If you’re trashing or burning (or even donating) your Nikes, just remember that Nike has already been paid for them. They’re not out one thin dime because you’ve decided to junk them and buy something else.
The smart way to boycott Nike is to use ’em till they wear out, then buy replacements from a manufacturer who doesn’t purposefully alienate a significant portion of its customer base. Get your money’s worth first, and then spend your money elsewhere. And be sure to tell anyone who asks about your Nikes that you’re only wearing them because you don’t see the point in throwing them away and spending money you don’t have on new ones. There’s no shame in being frugal.
I quit buying Levi’s years ago, too, when they first started getting ideologically squirrely. I’ll admit to buying a couple pair off of Amazon a couple of years ago, when I was having trouble finding jeans that fit, but what I got were of such poor quality that they’ve been reduced to serving as work pants at this point. But I won’t stop wearing them just because Levi’s has now upped the ante on their Second Amendment stupidity. There’s still some use left in them for dirty jobs. But otherwise I’ll wear the ones I’ve been buying from Duluth Trading. Yeah, they come from China. So what? So does damn near everything else. (And yes, I’ve tried USA-made Texas Jeans; nice, but they really don’t fit me right, and I can drive up to Noblesville and try on and buy DT off the rack.)
But don’t bother with the quintessentially lefty tactic of cutting off your nose to spite your face. No publisher ever cried over book burnings; they got their money, and now the book burners just have empty shelves. And Nike and Levi’s certainly aren’t going to cry over you trashing merchandise you already paid them for.
If you’re going to boycott, for the love of God, boycott smart. Even my lefty wife gets that (and said so this morning as she laced up her Nikes for work — “Glad the new shoes I just bought were Skechers and not Nikes, but I’m not throwing these Nikes away till they wear out — and anyone at work who says anything about them can bite me”).
As for me, I’ve never owned a pair of Nikes and likely never would have anyway. But I haven’t worn sneakers for quite a few years, either.
