Triathlon Socks

What are the best triathlon socks?

They may seem like a trivial thing but they are critical. Get the wrong socks and you will end up with blisters and lots of discomfort. Also, the right socks will help in a faster transition – specifically if they are short.

I like short socks as they make fast transitions easier.

#1 Choice: DeFeet Aireator

In terms of brands, I like DeFeet socks. These can last me a long time and put up with a lot of abuse. Running, cycling, and even everyday use. Plus, they come in really cool designs and colors.

For cycling, I specifically like the Aireator line. For tri, I go with the shorter lengths for faster on/off action.

#2 Choice: Asics Speed No Show

I’ve also had really good success with the Asics Speed No Show socks and have used them in multiple races. They’re cheap and they get the job done. They dry fast, are easy to put on and off, and are unisex.

The material is woven looser than the DeFeet, so they’ll wear out earlier, but the Asics socks may be better for hotter climates.

#3 Choice: Decathalon Wool

When I raced in St. George, Utah, in the 70.3 World Champs in 2022, it was kind of cold. So, I went for these wool sports socks from Decathlon because I figured they would dry out fast, and they did. Plus, they are really cheap.


Whatever pair you go with, consider the following factors:

  • Length – There is really no advantage to longer socks when you are pressed for time in T1 putting them on.
  • Material – Opt for a synthetic that wicks away sweat – avoid pure cotton. Wool can be really good at this, but it may be hot.
  • Weave – Tighter, closer-knit weave makes for a more durable but heavier and hotter sock.
  • Price – I find that going for more expensive options can probably actually save you money in the long run, as they may last you longer – you get what you pay for.
