My biggest discomfort when it comes to hunting is my feet and when they get cold or wet my hunting fun slowly turns to a job trying to keep comfortable.
In my opinion wool socks are the only socks you should be using while hunting. Any other socks do not provide the proper insulation and if they get wet all they are good for is giving you blisters. A common myth people share is that cotton socks will keep you cooler than wool because of the lighter fabric but I have noticed that wool socks in summer are the better choice for their insulating value and their water wicking ability. Synthetic material in my opinion are not the best choice for your feet but they are better than cotton for hunting purposes as they possess some water wicking and insulation value but are not as comfortable and effective as wool in my opinion. I have tried a number of wool socks and synthetic blend socks over the years and have decided wool is your best hunting choice!
