This is a pair of women's UGG Knit Cardy boots in grey, size US 11. They feature a ribbed knit upper with three black buttons on the side, allowing for versatile styling. The heel and trim are made of grey suede, and the boots have durable rubber soles. The inner tag confirms the brand, size, and serial number 1016555. The soles show some signs of wear and dirt consistent with pre-owned footwear, but the knit and suede appear well-maintained.
