A few weeks ago I picked up my first sponsor and was super stoked. Most of the ultrarunning world knows of Drymax as the company is both highly active in the community as well as highly used. After exchanging a few emails with Bob, I received a box of about 15 pairs of socks, all different kinds, to test out. To be honest, I had no idea they even made so many different styles, and it took me a while to even get through running in them all. For example, they've got 3 separate styles for trail running alone!
I'd previously run in the traditional trail running version and the hyper thin running, so I knew I was getting into a product that I could believe in. After going through all of the test samples, I found that all the socks I ran in were meritable on their own, but that I definitely had a two favorites: the Running Mesh Lite, and the Trail Running Lite. The styles allow you to pick a certain sock for a specific type of run if you're into that kind of thing, and they've got cold weather socks and hot weather socks and everything in between (literally). I wore the Trail Run Max Protection during Way Too Cool and despite running through water/mud for 31 miles with a terrible shoe selection, I walked away with no blisters or any other foot issues.
Perhaps you're like me and you are wary of people who are sponsored saying, "I wear this, you should too!" Don't take it from me, there is a reason a large portion of the ultrarunning world uses Drymax, and it's because they work, period. While they are going to cost you some money, they're cheaper than a lot of other performance sock brands like Smartwool. The multiple styles allow people to find what they prefer, but I'd say, if you don't take it from me, talk to someone who wears a pair who is not sponsored (they won't be hard to find).
