If you need to wear socks, then these are perfect.  Your feet never get too hot or cold!  I live in Florida and often go from cold a/c office to warm outdoor weather, and I never notice my feet getting too warm or too cold.  Before I found this brand, I often froze my toes off at work, and then too hot outside!  Also, no wear obvious, my other socks would wear thin at the heal and toes. Not itchy either.  Well worth the price!!!  Last longer, and more comfortable.
