Walking barefoot, or in flimsy shoes without sufficient arch support, can overstretch, tear, or inflame your plantar fascia.

Problem: Plantar Fasciitis A band of tissue called the plantar fascia runs along the bottom of the foot. It pulls on the heel when you walk -- and it works best with the proper arch in your foot. Walking barefoot, or in flimsy shoes without sufficient arch support, can overstretch, tear, or inflame the plantar fascia. This common condition can cause intense heel pain, and resting the feet only provides temporary relief.
Better: 'Fitted' Flops
Sporty, fitted sandals and other "toning shoes" are designed for a more intense workout while walking. The American Council on Exercise says there's no evidence to support that claim, but they may have other benefits. The thick sole keeps your foot off the ground and away from debris. And Brenner points out, "they do have really good arch support." Several have a seal of approval from the American Podiatric Medical Association.
