I used to wear the neoprene booties but it drove me nuts that they frayed so easily when you walk, and also that they get so sopping wet. Someone at REI told about Sugoi Resistor Booties, and I'm a total convert. They are reasonably warm, keep your feet VERY dry compared to the neoprene, and don't fray when you walk on them. http://www.rei.com/online/store/Prod...ry_rn=40004205
