I prefer the slide style so I can wear them with socks when the temps drop.
Most important to me is lightweight and fast drying. Velcro closure would be a bonus.
Looking at zappos, the best thus far is:http://www.zappos.com/nike-benassi-swoosh-black-white
Not sure many people in the lightweight section really bring camp-shoes. Most will just loosen their trail-runners or put on down boots (in the winter). I know a few people who use crocs or water-shoes.
I guess for "slide" style camp shoes there really isn't a market and they are all about the same in cost and weight.
