The UGG Classic Ultra Mini Boot is one of UGG's most beloved silhouettes, featuring a low-cut 3.5-inch shaft for effortless on-off wear and a timeless aesthetic. Available exclusively online at Costco, this listing is offered in Chestnut (Tan) and features UGG's signature 17mm Twinface sheepskin upper for durability and natural warmth.

The interior is lined with 17mm genuine sheepskin and an UGGplush insole crafted from upcycled wool blended with TENCEL Lyocell fibers, delivering exceptional all-day cushioning and coziness. A rear heel pull tab makes it easy to slip on, while an asymmetrical topline with overlock stitch detailing on the seams and a suede heel counter add a distinctive, refined look. The boot comes pre-treated with a post-applied water repellency treatment to help protect against the elements and keep it looking its best for longer.

Underfoot, a lightweight Sugarcane EVA outsole provides flexible traction while reducing dependency on petroleum-based materials. Available in whole sizes 6 through 10, the boots fit true to size but may feel slightly snug at first, naturally conforming to the foot over time. Spot clean only. Imported.
