Blue Sparkly Women’s UGG Boots 💙 Waterproof soles!

Bought pre-owned from Poshmark and never worn because they were too tight 😢 I love them I kept them forever hoping that I could wear them but I believe they must be a size 6 even though they were advertised as a seven and there’s no indication of what size they actually are. I am a seven 7 1/2 I could fit my foot in them but I could never walk in them because they’re just too tight overall so I’m labeling them as a 6. See pictures for small flaws
