And let me tell you after 7 days of non stop partying and hiking with friends over a city that easily makes you trek 7 or 15 miles everyday or even more, my feet were soooo sore, like beyond description. Now that I'm a veteran and its now not my first rodeo I wanted a few things that could really give me that edge to keep me going for as long as possible, and I would put these on at night go to sleep and in the morning my feet felt good as new, ready to take on another crazy day (I also lathered my feet in aloe and lotion and tiger balm) but my feet felt like brand new after every night. I try not to wear them too often so I don't just wear them out like other socks because their so expensive, but I use them like a foot jacuzzi and I try to walk minimally while wearing them to prolong their use. Sometimes I wear em around the house in slippers after a long day too. Apparently athletes like copper sleeves for their elbows and knees and I'm looking into getting some of those too.
