Running socks are so important, don't underestimate their value!
Everyone focuses on their running shoes. They look at multiple options, test out a few and then finally go for the one that fits best (hopefully). But what about the humble running sock. How much attention do you pay to them? Find out why you should spend as much time choosing them as you do your shoes.

What's the big deal?
The foot is a complex structure made up of bones, joints, muscles, ligaments, and tendons. There are more sweat glands per inch in our feet than anywhere else in the body. Their function is to keep the skin moist and supple and regulate temperature when the weather is hot while you're running. Sweaty feet, mainly as a result of the wrong socks, are a factor in the growth of foot fungus, fungal toenails, and athlete's foot. None of these are especially pleasant and they can cause discomfort, rash, and itching, leading potentially to further complications, such as foot pain, open sores, infection, and thickened toenails. It doesn't matter if it's a short or a long run, you just must make sure you wrap your feet in the right materials.
What to wear?
There are so many options on the market these days it can be highly confusing. We'll try and demystify it here.
Warm weather running socks
Generally speaking when it's warmer you want to wear a lighter sock and for many runners that also means a shorter sock; anklet options are especially popular when the temperature climbs. These socks often have ventilation panels to help move the sweat away from your feet more quickly and they have a more snug feel. Their number one goal is to stop your feet sweating for all the reasons we discussed above. They are made from polyester and similar materials and are extremely lightweight.
Cold weather running socks
When the temperature drops it's time for wool. They are a bit thicker than the warmer weather polyester options so just watch for fit. You don't have to go to extremes and buy a half a size bigger running shoe to accommodate them but just be watchful they aren't too tight. They are great at absorbing moisture, so if they get it's not the end of the world. You can find socks that use top quality natural fibres such as merino wool that are perfect for running socks. They naturally breathable and sweat-wicking, as well as anti-bacterial, meaning a more odour free run!

Blister prevention socks
One of the irritations associated with running in the past was the tendency to develop blisters. Some runners were more prone to getting them than others and this was often because they were wearing the wrong socks. Now it's all changed. There are socks out there designed specifically to prevent the formation of blisters. They are made of one layer of fabric, but of two. The inner layer stays with the foot as the outer layer moves with the shoe, and in the process getting rid of friction on the skin and protecting feet from blisters. And they work!
Compression socks
Compression sportswear is now hugely popular. You can get compression T-shirts, tights and now socks. You'll have seen many elite athletes in leading marathons wearing long socks and these are the compression socks. So, what do they do? The right style of compression socks can improve blood flow, giving your legs an active, energized feeling and helps boost recovery. Some are made to be worn during running, others are for the hours (or days) after your big event, and still others are for medical uses beyond running, like battling edema, varicose veins, and for plane trips to combat deep vein thrombosis. When choosing a pair you will have more options than you can imagine. You'll need to review the performance fabrics used, breathability, cushioning as well as antimicrobial and wicking properties. And then there are the colours. Again there are multiple options so if look is important when you're running you'll be able to find a colour to suit the rest of your gear.

The next time you're in your favourite running store don't just walk straight past the sock section and head to the shoes. Stop and have a good look at what's available. Read the packaging and get to appreciate the difference these products could make to your running. They may seem a bit expensive but there is a lot of technology in there and they are still a fraction of the price of your running shoes. It will be a very good investment for sure!
