I would buy this again!!!

I love these mules-they're very cozy, warm, and comfortable, and I appreciate how easy they are to slip on. The Vibram sole is excellent and adds great traction. However, they do run a bit wide, and I don't like that even a single drop of water leaves a visible stain.

Will not buy again

Love the shoe, but the material rips very easily. 2nd time I wore them I opened my refrigerator door just barely across the top of them and the material sliced open.
