These socks actually work! I have struggled for so long to deal with dryness. I’m a big runner and workout every day and my feet get so dry and cracked and never have a chance to heal. After shower, I put neosporin on the areas that were really bad, and then put these socks on and went to bed. When I woke up in the morning it was like my feet were magically fixed! The only thing I will warn of, which isn’t a negative, is the size. I am a womens 9 1/2 shoe size. If my feet were any bigger then these socks would not fit comfortably. My heels would be coming out of them. Otherwise, they are soft, comfy, and definitely do the job!
