Thanks for your review request. First of all, these swiftwicks are therapeutic for my 70+ y/o feet. Frequently I experience paresthesias, cramping, neuritis and serious tactile sole sensitivities from the bunching and irregularities of other lumpy socks. I have hammer toes and plantar fasciitis which cause discomfort. I first wore swiftwicks about 10 years ago for biking and found them quite comfortable on long rides. Since then my feet have become much less tolerant of regular socks. So I started wearing my bike socks on a daily basis. I saw your advertisement on my phone and bought several styles and heights. So far I haven't tried them all but am perfectly satisfied with a few. Walking with limiting foot discomforts seems at a minimum now. Thanks and God bless us all. David M.
