Wish I could tell you Renee. I found them extremely stiff and uncomfortable, but it didn't bother Beth or many of the people who reviewed them. I also felt they were too tall for me (I am 5'2). My Stuart Weitzman boots are the same height but they hug my leg all the way up, whereas the Miz Mooz boots gaped around the top, which indicates to me that they weren't meant to be that tall. However, if you have bigger or longer legs than me they might work.
If a boot manages to stay up on its own and doesn't collapse after I take it off, odds are it is way too stiff and inflexible for my comfort, and that is exactly how the Kailias are.
