You need a massive pair of boots to climb Everest. They are a bit like ski boots in that they have an outer and an inner layer. I use La Sportiva Olympus Mons – they look like astronaut boots but have a good warmth to weight ratio (warm and durable without being too heavy) and are easy to put on with gloves.
