I've got a pair of Merrell shoes similar to these:
Merrell Vapor Glove Road-Running Shoes - Women's - Free Shipping at REI.com
The pair I have, I got on the clearance rack, so I'm pretty sure they are discontinued.
Anyway, these are thin shoes, meant to be worn sans socks. The shoes I have do have Vibram soles (the same Vibram that is famous for the Five Finger toe shoes) which I believe helps tremendously with the gripping, something about the way Vibram designs the soles. I got these shoes at REI, and they are quite comfortable. Being an owner of Vibram Five Fingers, I can honestly say that these shoes give the same feel as the toe shoes. Since they are thin, I am essentially using all of my foot's joints and muscles, just as I would if I were going barefoot. Think of it like wearing a thick, skin tight sock, or something. Ask the shoe section employees at REI, they'll tell you all about 'em.
I bet you can find a more modest pair as far as color goes, too!
Stumbled into Primal due to food allergies, and subsequent elimination of non-primal foods.
