UGG Classic Ultra Mini vs UGG Classic Mini

Both are UGG Classic Minis, so the real choice is shaft height and sole. The Ultra Mini has a 3.5-inch shaft with a rear pull tab, so it slips on fast and suits narrow ankles and quick errands. The Classic Mini has the taller original shaft and a thicker sole, which holds the foot better and lasts longer in snow and slush. Reviewers call both warm and cozy; the Ultra Mini draws more complaints about creasing and a cheaper feel, while the Classic Mini's 4.8 rating comes from a much smaller pool of owners.

• Choose the UGG Classic Ultra Mini if you want the easiest on-off boot for dry cold days and prefer the lower, sleeker profile.
• Choose the UGG Women's Classic Mini if you want the taller original shaft and a sturdier sole for wet sidewalks and daily winter wear.
