Never worn! Just a little too big for me. I’m generally a 10.5. From Oofos website: 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 Boot. Built on a foundation of the same patented footbed and OOfoam™ technology yOO love, this versatile winter boot 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. Delivering the features yOO want and the benefits yOO need, this lightweight, water resistant and perfectly packable boot was built for all your après activities. Feel the OO of this Active Recovery boot ... and get the most out of your multi-day or season pass this year!
