Thick socks do not necessarily mean warm socks. Alpaca socks can be warm socks even if they are not super thick socks. The percentage of alpaca content within a sock helps dictate the degree that the sock is a warm sock. For example, check out our warm Boot Alpaca Socks, which are made of 50% alpaca. They are not our thickest alpaca socks yet they are still very warm socks. These warm socks can easily be worn with casual shoes as well as fit comfortably into athletic shoes.
So, just like bigger is not always better, thicker is not always better – at least when it comes to warm socks. However, some people love the cushiony feeling of a thick sock. So, if it’s thick socks that you like, some thick, warm socks that our customers love are called Heavy Boot Alpaca Socks. We sell quite a few of these comfortable, warm, alpaca socks.
Alpaca socks are also warm socks because alpaca is a natural, semi-hollow fiber. The hollow core fiber weighs less than the same diameter solid core fiber of another type of animal. Because air is trapped in the core of alpaca fiber, the fabric warms up very quickly. As a result, socks made from hollow core alpaca fiber can be lightweight yet much warmer socks than their solid core equivalents. Make sense?
Yet another reason alpaca socks are warm socks is because they wick away moisture so your feet stay dry. We should mention here that wicking and absorbing moisture are two different things. Absorbing moisture is what a sponge does. It takes in moisture, becomes saturated, and the whole sponge feels wet. Wicking is when the fabric transports moisture AWAY from its source to the outside of a fabric where it then evaporates. Wool and cotton are absorbent but do not have good wicking properties, which is why feet can sweat or feel wet in wool or cotton socks. Alpaca socks, on the other hand, have extremely low moisture absorbency with great wicking properties.
