Thank you all - didn't get a chance to get back her yesterday and I really appreciate the input. I like the Eccos best out of the options so far but the Clarks look worth trying - except they aren't available right now in my size.
I really want leather, not canvas for durability and easier cleaning. My canvas UGG slip ons from last year were okay but didn't hold up as well as I'd like.
Superga doesn't really fit me for whatever reason (I've tried a few different styles) and DH doesn't like Adidas at all - so I didn't want to go there.
Here's hoping the next size up works in the Eccos!
