Problem No. 1: Plantar Fasciitis
"This is by far the most common problem I see in my middle-aged patients". Plantar fasciitis is an overuse syndrome that causes painful inflammation of the band of fibrous tissue that runs along the bottom of your foot (called the plantar fascia). "The force on your feet is about 120% of your weight". "Over time, that causes the tissue in the foot to become less elastic," leading to pain.
Problem No. 2: Bunions and Hammertoes
These painful deformities of the great toe (bunions) and smaller toes (hammertoes) can be genetic, but they get worse if you consistently wear too-tight shoes.
Problem No. 3: Calluses
While most of us think of these areas of thick skin as simply unsightly, calluses are pressure spots that can be painful when you walk, says Oster. Interestingly, they're actually the body's way of preventing painful blisters from developing.
