Uhhhhh.....
*whistles innocently*
I might like VFFs just a little, teensy bit.
KSO
I usually wear these in the summer. They're versatile, so I can easily wear them out hiking or out to the store. They do get a bit toasty on extremely hot pavement though.
Komodosport
These are the ultimate all-purpose VFF, and the style I recommend to everyone as their first pair. I wear them everywhere. The soles are a tad bit thicker than KSO soles, so they don't get hot in the summertime and mask the feel of sharp gravel much better.
Treksports
I wear these on short hikes, and occasionally to work when I happen to be wearing black pants. To be honest, the thick lugs on the toes of Treksports sometimes give me sore spots, so I wear these as infrequently as possible. I do like them when I have to spend an entire day on dirt for an agility trial though - they get excellent traction.
Trek
These are leather, and the only reason I bought them was because they are leather. This means I can wear them to work. These are probably the least comfortable, least attractive pair of VFFs I own. I don't like them, but they're a necessary evil. It doesn't help that they have Treksport soles, blech. These are discontinued - so if you want a pair, be prepared to do a lot of online hunting.
Spyridons
These are my dedicated running VFFs. The sole is quite aggressive and feels different than any other VFF sole I've tried. I do like them though.
Speeds
Speeds are my favorite "fun" all-rounders. I don't think I'd wear Speeds out on a hike, but that's only because I have other models better suited to getting dirty and nasty. These are based on the Bikila platform so they do have a tiny amount of arch support, but they're flexible and thin so you do get a decent amount of ground feel. I like wearing these when I want to wear fun shoes but not instantly get noticed for wearing "weird" shoes.
Bikila
I don't like them. The velcro is different on these, so the pressure points are different and I just don't like them.
Lontra
Currently my only water-resistant pair of VFFs. They're built on the Treksport platform (darn it!) but they do seem to fit well. If I wear socks with them, my toes go numb. I really don't like them, but they serve their purpose of me not having to switch to normal shoes in the winter.
