Sock fit is very important for the comfort of your foot in a shoe.  Begin by considering the correct sock size based on your shoe size.  Then, consider the shoes that you want them to fit inside and the thickness of the sock you would like to purchase.   Avoid socks that make your boot fit too tight.  Also, avoid socks that bunch up and, ultimately, rub your foot and creating blisters.  It is advisable for women to purchase a women’s-specific sock to better fit a higher instep, narrower heel and lower volume foot.  Everyone will find sock liners useful because they provide a wicking layer for drier feet.  Also, thick socks, regardless of the air temperature when you are hiking, are important for absorbing moisture when you are hiking.  This will keep your feet drier and help you to avoid blisters.
