I like to walk, touch living Mother Earth—bare feet best, and thrill every step. Used to envy happy reptiles that had advantage of so much body in contact with earth, bosom to bosom. [We] live with our heels as well as head and most of our pleasure comes in that way. – John Muir, quoted in To Yosemite and Beyond: Writings from the Years 1863–

In the morning a man walks with his whole body; in the evening, only with his legs. – Ralph Waldo Emerson

Walking takes longer… than any other known form of locomotion except crawling. Thus it stretches time and prolongs life. Life is already too short to waste on speed. – Edward Abbey, “Walking”
