“Most of the men wore heavy Burberry-Durox boots—ankle high leather boots with gabardine uppers reaching to the knee—designed for marching on hard ice. But as the party struggled over the slushy floes, those boots continually filled with water. In the soaked state, each weighed about 7 pounds. It was an exhausting exertion at every step to lift one foot and then the other out of 2-foot holes of snowy slush.”
