Ending up with wet socks can be quite painful in certain situations. That is especially the case if you are spending time in very cold places. Keeping your feet protected in freezing conditions is very important. These waterproof socks keep your feet dry down to temperatures as low as -30º F. They have an outer layer of nylon/Lycra and a waterproof middle layer. These are pressure tested to protect against leaks. These socks cost $55 a pair.
