Criteria Used for Evaluation

Insulation

One of the most important aspects that makes any heated sock successful is whether or not it has insulation. Conduction (the type of heat transfer insulation in your socks) is what keeps your feet warm inside your footwear. It uses the heat your body naturally produces and stores it to protect against the cold while also regulating your body temperature to prevent overheating. Considering overheating causes sweat and sweat makes you colder (and makes your clothes stink) this also keeps your feet toasty while smelling and feeling fresh. Without insulation, your socks will not keep you safe from freezing temps, so if a company claims their socks are "thermal" but don't have some form of insulation they are not heated socks. Don't buy them unless you're looking to be disappointed.

A variety of materials can provide proper insulation. These include wool, fleece, Thinsulate, and flannel. Different material will have different heat retention properties and will be suitable for different levels of cold. For example, Thinsulate is a better insulator for extreme cold than wool, and well-knit wool is a better insulator than most flannels.

The higher the score on this metric, the better the insulation the sock offers. Usually, those socks that score higher on this metric are made of the fabrics we discussed above.

Materials

Since heated socks are worn during vigorous activity, it’s necessary that they can take a beating (as the saying goes). This is exactly the reason companies reinforce their fabrics so that their products are up to par. You may ask how they reinforce the fabrics, and the answer is; it's all in the techniques used to weave the yarn. Using the wrong loops and stitches can ruin a perfectly designed garment, making it more likely to fall apart after one wear and wash. Another important aspect is whether or not interface fabric is attached to the main fabrics.

Regular socks are typically very thin and used for protection against the dirtiness inside your shoes. Thermal socks, on the other hand, are usually thicker, more heavyweight and heavy duty, guaranteeing the comfort and warmth you're looking for. If the socks are nice and thickly knitted, then it retains heat better and resists cold a little better. It's critical that the heated socks be "cushy" compared to regular socks to keep warm in the coldest climates.

Socks that score higher in this category tend to be heavier and warmer. If you are looking for a sock that will keep the cold away, you’ll most likely want a sock that scores higher in this criterion.

Size

The thickness of the sock depends on what the sock was made up of and its intended use. If a sock was intended to be worn under dress shoes in the summer, then you will not find the socks to be very thick, and you won't find them on this list.

Socks on this list are made up of material that is good at trapping heat, such as wool and cashmere, but sometimes they are also mixed with other materials, such as polyester or nylon, to give a bit of stretchiness to the sock. Socks need to be easy to put on and fit around your feet, and it’s very hard to make a material like wool naturally do that.

Thinner socks are usually made for conditions where breathability and temperature are of utmost importance, whereas socks on this list are often thicker, to retain heat in cold conditions. The higher the score on this criterion, the thicker the sock is. While this can be good for heat retention, also consider what kind of shoes you'll be pairing your new socks with. You might need to rely on the material more to retain heat if your shoe can't provide the space for a thick fabric to trap heat.

Fit

How a sock fits should greatly affect your decision in whether to buy that specific sock or not. The right socks should fit comfortably on the heel, not over or under it. The right ones will not bunch at the top or be falling at the shaft. These signs often point to faulty manufacturing than to how your feet are shaped. The height of the socks will depend on what you wear. If you’re wearing shoes that touch your ankles or go over it, then it doesn’t do much good to wear socks that go below the ankles, except in a very few cases.

To make it easier in buying socks, there are names for socks at certain heights. The smallest of the bunch is the roll top or the low-cut sock, which has the top at 3” from the heel. Then there is the sport or sportlet tab, which has the top at 4” from the heel. These socks usually touch the ankle. There is then the quarter socks which go above the ankle at 5” and above. Crew socks come next, covering most of your shin and calves at 11”, and there are the hi-crews, which touch your knees and go above them at 15” and more.

The higher the score on this criterion, the better the sock, whatever its length, fits around the foot and gently compresses it for added support.

Comfort

Finding a comfortable pair of socks that wrap your feet in luxury and support with a good level of compression is essential for comfortable feet. When you are trapped in your shoes or boots all day, you need a layer of hygienic, moisture-wicking and heat-retaining socks to keep your feet smiling. An overall combination of the other criteria we evaluated our top 10 for, comfort is dependent on the quality of the materials, the thickness and breathability of the sock, it's fit and also the uniqueness of the wearer.

Materials like cotton are breathable and easily absorb and wick away moisture, making them a prime choice for the construction of socks. Materials like silk are much more luxurious and have a great feel against the skin, but are much harder to source due to supply constraints. Which material you prefer will depend on your budget and your situation. When evaluating our top 10 for comfort, we considered the material and the versatility of wear the sock offers.

We've ranked comfort based on thousands of customer reviews from all over the world to give you a general impression of what people are saying about the product, but at the end of the day, you know yourself best. Trust your gut!

It isn't very often you can find a thermal sock that advertises it can fit adults and children. DG Hill does. They say their extra small fits little kids sizes 9.5-13, therefore your little guy or gal can match mom and dad while staying wonderfully toasty. No more anxiety about letting little ones jump in puddles and walk through snow mounds.

I've noticed that when your socks start to give up the ghost, they go out heel first. DH Hill must have noticed this too because they reinforced the fibers in the heel of the sock for extended wear. Their lifespan is longer than the average heated sock, and with three pairs in a pack, you shouldn't have to buy more for quite some time. Unless your family is like ours and doesn't do laundry until you've ran out of clothes, then you'll need several more packs.

Extensive walking, standing, or being on your feet, in general, can take it out on your arches. At the end of the day, you feel like your feet are ready to snap in half from lack of support. Thermal socks are so thick it prevents any extra space inside your shoes which makes added insoles a no-go. DG Hill took this into account and added built-in arch support for the working man (or woman).

No need to layer sock upon sock because once you put these on you'll forget what cold feels like.

When you work and walk (and work and walk) your socks wear down and thin out, then the holes appear.
