I am back out here buying more socks. I have a problem foot with a bone spur and Achilles tendonitis. I have tried everything KT tape, tens unit, massage, stretching. I noted that I did not have any pain on my hiking trip 2 months ago, but after I got back it was bugging me again and couldn't figure out why. Yesterday put on the hiking socks even though I wasn't hiking. OMG the socks really help. They are worth every penny. I also did get any blisters in my Merrell boots, or the socks and my friend had some bad ones. Lover everything I bought from Merrell.
