Criteria Used for Evaluation
The wool of the Merino sheep is not the scratchy itchy wool of the Christmas pullover your Grandmother knitted for you, Merino wool is soft.
It is the thickness of the fibers of the wool which makes it feel itchy; Merino wool has a much smaller diameter than other wools, which enables the fibers to be more flexible and bend easier. Thicker fibers of other wools are less able to bend and flex and this makes the ends of the fibers prick the skin, and although the fibers are never going to penetrate the skin, the body's natural reaction to this is to make you feel an itch. Merino wool is so much thinner in diameter and this means that it doesn't prick the skin.
Choosing the best Berino wool socks is a personal thing. And as will all items of clothing, personal style and color preferences are individual and important.
Many Merino wool socks will state they are Merino wool sock and they are, but the amount of Merino wool is less than 50%. Although Merino wool is very flexible and strong, it does not have the elasticity of Nylon or Polyester, and the compression needed for a good compression sock will mean that over 55% Merino wool content is not possible.
Wool has the natural ability to trap dead air, the more air you can trap the better the insulator.
Even when wet, the wool’s ability to move the moisture away from the skin enables excellent heat insulation. And because wool is a breathable fabric, it will help to keep you cool. And if you suffer from smelly feet, wool socks will help. The odor of smelly feet is caused by bacteria, bacteria need a moist and warm environment to grow and live; we have already covered that wool is excellent at removing moisture, so the bacteria cannot increase enough in number to cause the odor.
Wool also offers natural sun protection, the wool absorbs the UV radiation that damages skin and Merino wool has an SPF 40+, but obviously, the weave density is also important and can affect this.
Your feet are going to be in a pair of socks and stuffed into shoes or boots. Then you are going to walk, run, jump or climb. You want your feet warm in the cold and cool in the heat, and in both cases, you want your feet dry.
Hopefully, your shoes or boots will keep your feet dry from the outside environment, but sweat is how your feet may become wet from inside your shoe. This is not good as it can promote blisters, bacterial and fungal growth, and other uncomfortable conditions. As you all know, you need a fabric that is breathable, a fabric that is able to transport moisture in the vapor state away from your skin, which means Merino wool socks are the perfect choice!
Expert Interviews & Opinions
Arch support or elasticated arches are a nice feature. This prevents the sock from bunching up inside your shoe, which can cause friction blisters.
