Best running socks for triathletes

A good pair of run socks are key for maintaining foot comfort when running. Here are 3 of the best

Running by the coast

We put so much time, effort and money into purchasing the right running shoes, yet often seem to ignore the value of picking the best running socks for our feet.

It’s a strange scenario, as running socks can have a huge impact on the comfort and support that are feet are subjected to. So with that in mind, we’ve pulled together a list of the best running socks on the market right now.

Best running socks

Runderwear Anti Blister Socks

Runderwear Anti Blister Socks
  • £15

This offering from Runderwear is designed specifically with the task of reducing the risk of blisters and, in our experience, it does that with aplomb. This is due to the two-layer construction, which reduces friction forces on your foot.

It works well, though pulling these socks on did require a little more care and attention to ensure no bunching of the inner layer, which could add unwanted seconds to your transition time. Once on and correctly in place, the socks were really comfortable. There’s a decent amount of cushioning and the result is a plush running experience.

Due to the double layered nature of these socks, they do run a little warm and moisture wicking isn’t quite as efficient as other socks in this test. However, we didn’t find that an issue on our shorter training runs.

Verdict: Impressive blister protection, but not the quickest for pulling on in transition.

Score: 86%

Darn Tough Run No-Show Tab Cushion Ultralight Running Socks

Darn Tough No Show Cushion running socks
  • £16.95

These running socks were just a delight to run in. They have cushioning in all the right places, which helps deliver a plush running experience. A cushioned heel tab ensures the sock doesn’t slip down into the shoe and also helps get these socks on quickly when in transition.

The close fit ensures it’s hard for dirt to get into the sock, but that heel cuff occasionally caught debris. A blend of nylon, Merino wool, and lycra makes for a good balance of durability, comfort, support and anti-odour properties, while the seamless construction boosts comfort further.

As with all Darn Tough socks, these come with a lifetime guarantee, though this is something we’ve never had to utilise before.

Verdict: Hard to fault; excellent, comfortable running socks.

Under Armour UA Armour Dry Run Crew Socks

Under Armour UA Armour Dry Running Socks
  • £15

These socks from Under Armour are unlike many on test here in that they have a high ankle cuff. This is great if you’re running on trails, as it offers protection against nettles and brambles, as well as dirt finding its way into your sock. That being said, the white colourway we have on test here doesn’t stay clean for long.

Under Armour says these are their fastest drying socks and, while we can’t verify that, we can say that they managed moisture very well. They’re also well ventilated thanks to mesh panels on the top and bottom of the foot, though the higher ankle is slightly warmer than no-show socks.

We found them to be comfortable, with a secure fit ensuring no bunching of the fabric. There’s slightly less cushioning than the likes of the Darn Tough and Runderwear socks on test, but we didn’t find this detrimental to comfort. Meanwhile, there’s arch support to help with foot fatigue.

Verdict: Great support, ventilation and moisture wicking.

DexShell Running Lite Waterproof Socks

DexShell Lite Waterproof running socks
  • £24.99

Waterproof socks can be a good option in harsh winter conditions, keeping your feet warm and dry, and DexShell are one of the industry leaders in this regard. On test here is the brand’s Running Lite Waterproof Socks.

As with all waterproof socks we’ve tried, comfort levels aren’t quite as high as standard socks, but these were certainly not uncomfortable, and we had no issues with wearing them. There was ample cushioning and good arch support, but the fit isn’t quite as close as standard socks.

Weather protection is good, as expected, but unless it’s particularly cold, you should expect to end up with sweaty feet, which is what happened on our test runs. Based on this, we’d recommend saving these for properly miserable weather days.

There were no issues with durability and we liked the added visibility on offer thanks to the colourful band at the top of the ankle cuff.

Verdict: Great for particularly cold, miserable weather, but can get sweaty inside.

Monkey Sox Ultra X1 Sport

Monkey Sox Ultra X1 Sport
  • £16

What can we say about these socks. Well, a lot as it happens. The first thing to note is that 50% of profits generated by the sale of these socks are donated to multiple sclerosis charities. We think that’s incredible, and we’re sure you will too, so these socks are a great choice for those with a conscience.

The next thing to note is that these socks are bright. Very bright. And there’s a monkey on the back too. While that might not be to the taste of everyone, we found it good for visibility and, despite normally wearing subdued colours, we soon began to embrace the madness.

Comfort-wise, these socks are luxurious to wear. It’s like sliding your feet into your favourite pair of fluffy slippers. Cushioning is good, while the 1/4 cuff helps keep out debris. They were quick to pull on too, making them a reasonable choice for in transition.

After sustained use, we noticed the fabric started to pill, but at this point this seems to be purely only an aesthetic issue and the socks have continued to perform as expected.

Verdict: Super comfortable and we love the charity involvement.

Smartwool PHD Run Light Elite

Smartwool PHD light running socks
  • £17.99

Made of a mix of Merino wool, nylon and elastane, these socks are designed to be offer excellent durability and performance. In testing, we saw nothing that suggested otherwise.

Thanks to the targeted cushioning on the ball and heel of the foot, mesh ventilation zones and a ‘Virtually Seamless’ toe, these socks were extremely comfortable. With Merino wool making up part of the construction, they remained odour-free and remained warm when wet.

There was a great deal of support on offer, while the close fit meant there was no issue with dirt or debris sneaking into the sock. Thankfully, they’re also quick to slide on, making them a reasonable option for race day.

Verdict: Not cheap, but high quality and comfortable.
