Cotton Kills.....Runners Beware

I've always been a runner, that being said, it wasn't until this year that I've become a long distance runner and completed several marathons. There is a difference in going out to do an easy 5 mile jog and completing a training run of 18 miles. Last year when I was training for my first marathon, I kept getting blisters on my feet. I just assumed that it was part of the training and running longer distances than I've done in the past. It wasn't until I was telling my friend in my running group about it, and he said “It's because you are wearing cotton socks”.

From that day on, I stopped wearing cotton socks. Now I'm not here to tell you that you will never get a blister by not wearing cotton socks, but it does make a huge difference. So if you're not wearing cotton socks, what type of socks do you wear? Synthetic. I never liked running in thin socks, that's why I've always chosen a thick cotton sock, but it wasn't until I went to look for synthetic socks that they do come in thick as well. Brands like Thorlo and Smartwool are well padded at heel and toe. If you want a thin sock, brands like Defeet and Patagonia are a great choice. My personal favorite are Asics. Whatever your preference, you will be able to find socks that fit well that are not cotton. In addition to socks, same goes for your workout attire. Try not to wear anything cotton for long distance running, you run the chance of chafing. To help prevent chafing, try applying Bodyglide to areas that may become irritated during your run. One rule to remember.....Cotton Kills!

Am I the only one that didn't know not to run in cotton socks?

Label on socks. Notice there is no cotton listed!


  1. A running store employee once told me "Cotton is rotten."

  2. I admit, I run in cotton socks :( I haven't any problems yet but I think I will switch up
