<!--paging_filter-->Your most important piece of ski gear? Ski boots, of course. But make no mistake: Your ski socks are right up there. As with base layers, the form and function of a sock begins with its fibers. Organic fibers such as wool or silk generally have superior warmth-to-weight ratios, even when wet. Synthetics, such as nylon and Lycra, wick moisture and are highly elastic to help socks hold their shape. Most socks have some combination of synthetic and organic fibers. Not sure which to choose? We've picked out 12 ski-specific socks with different functions you might be searching for - performance, warmth, and support. This should help you get started.—Lauren Parker, Contributor, SKI Magazine
