Earth shoes were designed by a Scandinavian yoga instructor in 1957. The shoes are made with a "negative heel," the heel being lower than the front in order to minimize foot pain and make for better posture. Many people enjoy Earth shoes, including Manolo Blahnik, the European shoe designer. Reviews from customers praise the Earth shoes' comfort and report fewer foot problems and backaches among some users.

On the Other: They Don't Fit Some People Well

Despite Earth's best efforts, some buyers of Earth shoes, especially those with larger or wider feet, simply find them uncomfortable. The website Zappos, which sells Earth shoes, carries customer complaints regarding different models of Earth shoes, ranging from them being too narrow and small for the size they're labeled to the boots taking several minutes to put on.

Bottom Line

Earth shoes were designed for comfort and to promote superior posture. Some people do find them too narrow for larger feet and too small for the size they are supposed to be. Earth shoes have many fans, though, and most reviews by customers report positive experiences with the shoes, praising their comfort and reporting fewer foot and lower back problems after wearing them.
