The Adidas mountain bike ones are good because there's so much room on the underside of them for treads on your shoes to stick out through. The Pearl Izumi ones are nice too, but really ... anything will work. Maybe it's a wind shell vs. neoprene thing.
For temps ranging through the 40s and 30s I use some cheapo performance toe covers, just to cover up the mesh on my shoes. For temps well below freezing, I use the Pearl Izumi Toester full-on neoprene booties and thick wool socks. That combination keeps me going when its well below freezing. If there is freezing rain or slush, I slip a plastic bag between my booties and my shoes...that keeps my feet warm and dry.
