For best fit, we recommend sizing a half-size up to make room for generally thicker winter socks.

It’s BACK, and BETTER! Introducing the NEW Women's OOmg Bootie. Built on a foundation of the same patented footbed and OOfoam™ technology yOO love, this versatile winter bootie has a new and improved fit. Featuring a more secure heel and midfoot lock, it retains a relaxed and roomy forefoot that’s intentionally designed to provide maximum mobility, enhanced warmth and optimal recovery. This lightweight, water resistant and perfectly packable bootie offers the same benefits as the Women’s OOmg Boot in a style that is shorter and hitting just above the ankle. Feel the OO of this Active Recovery bootie ... and get the most out of your multi-day or season pass this year!
