Glad to see I'm not the only one in love with these
Number 3 is the one that caught my heart because of the slightly "folk" vibe of the different materials and panels. But I was concerned about what Chris987 said--if the laces make them less versatile, more "military" perhaps. My second favorites are the first ones, especially because you can fold the rim down or wear it up. The ones in the middle seem to me the most versatile and have very beautiful clean lines, but are not as whimsical. My size doesn't have a lot of color options, but like JAileen I also loved the white ones.
I normally don't obsess soooo much about clothing items (OK, I do, sometimes), but I feel like I didn't do my homework three years ago when I moved to MN and bought my current snow boots, so now I'm covering all my bases. I've been slightly dizzied by the number and variety of brands, models, options, etc...
