Would it be weird if a vegetarian wore Beach Feet Australian Boots?!

If a vegetarian wore Beach Feet/Uggs they wouldn't be a vegetarian. Sheep are KILLED for Uggs.
Vegetarians are against animals being killed, not just for meat. Vegans don't have any animal products, e.g milk.
But some vegetarians don't mind wearing dead animals on their feet.

am a veggie

If you already have them, you may as well continue to wear them until they're old or pass them along. Otherwise, I suggest you look at other vegetarian options like at Alternative Outfitters. I provided you a link for that in your other question.

When you shop, you are considered a "consumer." That is because consumption doesn't only refer to eating. You'll want to consider your ethics and morals before making any purchase, and that is true of everyone- Not just vegetarians. Does buying this pair of shoes fit into your moral make-up? If not, is it worth it to buy them? Are there other options available that do fit into your belief core?

I hope you find a pair of boots that you like and enjoy, and also ones you can feel good about purchasing.

i don't think you could say it would be "weird", because no ones really gonna know or pay attention to that. buuut, it does go against all of vegetarian ethics and stuff. it's kind of worse than eating meat; eating is one thing, but wearing an animal i find very unnecessary and cruel, because it really didn't deserve to die to become a shoe.

dear it's not weird ,as long you don't eat the boots,

Im a strict vegetarian and i wear uggs. Its not exactly like im consuming the boots....
