Are Fake Uggs Fashion Boots, Are They Okay For Lots Of Snow(read Description <3)?

I’m going to camp this Wednesday and it is in a place up north in Canada with lots of snow. Is it okay if I use the fake Uggs( those are $30 ones) for camp? Or are they just fashion boots not meant for snow? By the way inside theres insulation which means the inside is covered with wool. Will I freeze there? HELP
Remeber the uggs are fake, so they might not be as warm as the real ones
