Part of the Classic Slim™ Collection, this evolution of the Classic Mini features premium materials, expert craftsmanship, and signature comfort in a slimmer silhouette. Rendered in plush materials that have been pretreated to repel water and stains, the Kristin also features added arch support, a small wedge, and the innovative Treadlite by UGG™ outsole for incredibly lightweight traction, cushioning, durability, and flexibility.

It is designed to be worn with bare feet, but if you would prefer to wear it with socks, consider ordering a half size up.
