Well, wearing socks when trail running is a personal preference. There are differing opinions about this subject, but the best way to go about this is to give it a try yourself. Find what works for you. If you go trail running without socks, you may experience some skin irritations that may be taken care of when you use some liniment. However, to avoid further mildly painful experiences like this, you should consider using some runner’s tape on specific problem areas before you hit the trails again. Some experienced runners will advise that you should go trail running with socks while other veterans will advise against it. So, the best thing to do is to try it out: find what works best for you and stick to it till the end.
