It’s true that most shod humans are not currently adapted to walk or run barefoot on hard surfaces such as asphalt or concrete, but that doesn’t mean we don’t have the capacity to do so. Our feet are remarkably adaptable and can, with time and careful exposure, learn to tolerate a wide variety of surfaces—soft, hard, smooth, or bumpy—as long as the foot is strong and free of acquired, footwear-induced deformities.
A great example of humans who have adapted to hard surfaces are the rickshaw pullers of South and Southeast Asia. These are individuals who are often walking or running barefoot on hard and irregular surfaces while towing considerable weight. In his article entitled “Children’s Footwear: Launching Site for Adult Foot Ills” published in Podiatry Management magazine in 2002, renowned podiatrist and natural foot care advocate, Dr. William Rossi, says the following about barefooted rickshaw pullers:
A century ago, the rickshaw, which originated in Japan, was the common means of transportation in many Asian cities. In 1910, some 18,000 rickshaws and 27,000 rickshaw men were registered in Shanghai alone. The rickshaw men, most of whom began their occupations in their late teens, averaged 20-25 miles daily, trotting barefoot, mostly on cobbled or paved streets and roads. Many stayed at this occupation for 40 or 50 years. The feet and arches of almost all were healthy and exceptionally strong.
In the same context are the tens of thousands of workers who daily load and unload ships while working barefoot on the docks of such coastal cities as Singapore, Jakarta, Bombay, etc. They carry back loads as heavy as 50 and 60 pounds on their shoulders, walking barefoot on the thick planks. And rarely a foot or arch complaint.
The tenacious myth of the negative effects of unyielding ground surfaces is long overdue for burial.
Dr. Ray McClanahan, the inventor of Correct Toes, also tells the story of young children in Liberia, in West Africa, who regularly play soccer barefoot on the pebbly ground without issue. And Dr. Marty Hughes, co-founder of Natural Footgear, recounts his experience on the trekking trails of Nepal, where he witnessed barefooted mountain porters carrying exceptional loads over all kinds of surfaces, including long sections of boulders and scree. So, it’s clear that the human foot is indeed capable of safely tolerating a wide variety of surfaces, including harder surfaces, such as stone, asphalt, or concrete.
As it is, most minimalist shoes provide at least some level of protection for your foot’s sole. Though you may feel certain things (e.g. rocks, pebbles, roots, etc.) under your foot when wearing thin-soled footwear, it’s usually the sensation of pressure (tolerable) rather than pain or discomfort (intolerable). Wearing minimalist shoes also favorably shifts the way you walk or run, reducing the loading on your joints and tissues, which can make the overall impact forces associated with foot strike significantly lower.

Through our own personal experience (and through the experience of helping other people adapt to minimalist footwear), we’ve found that most humans do indeed have the capacity to walk or run on modern surfaces—surfaces that may or may not include variables such as rocks, roots, and cracks—once the foot and lower leg is sufficiently conditioned.
