A pair of fully waterproof knee-high rubber boots with sturdy, high-traction soles are essential. We stress the importance of boots that are completely waterproof so that your feet will not get wet when you step into shallow, icy water during wet Zodiac landings. Additionally, boots should have good traction because you are likely to encounter poor footing on ice and rough terrain. Comfort is important—if your boots are too heavy or bulky, your footing will be awkward during hikes. Also, good walking shoes such as sneakers are essential.
