Use a shoe stretching machine. If trying to break in your high heel shoes doesn’t seem to be working. Or if you simply don’t have the time try various DIY methods, stop by a shoe repair shop for a quick fix. Shoe repair shops have machines specifically built to stretch your shoes. The machine applies the same techniques as common home remedies –pressure and heat –to stretch your shoe quickly.
"Taking breaks at regular intervals is mandatory" Once, years ago, I attended a movie premier gala for the second "Sex in the City." Of course, high heels were required attire, and mine were very high! There were very few places to sit at the gala, and I must have stood in those heels for over two hours straight before going into the theater. The first order of business was to remove my shoes after finding my seat, and I spent the whole movie stretching my feet, as it says to do above. When the movie ended, I gathered my shoes from under my seat, feeling revived enough to make the two-block walk back to the car. But, hard as I tried, I could only get one of the shoes to go onto my swollen foot. Walking with one leg 5" longer than the other was not an option, so I made the trek barefooted. It was raining when I left the theater, and although I first met it with an "Oh, Sh*t," I quickly found that the puddles were welcomed finds along the way, as the cold water felt so good to my feet. ;-)
Blast your heels with heat. Heat is an effective way to soften a material and make it more pliable. Carefully warm your heels using a blow dryer or a small heater for about a minute or two. Watch how your heels react to the heat because certain materials don't do so well under heat for long periods of time. You can bend and twist your heels while they’re still warm. Or you can wait until they’ve cooled and put them on with a pair of socks to stretch them.
"Wearing high heels changes the natural biomechanics of the foot which has been honed by thousands of years of walking," he explains. "We also walk on concrete all day every day, which is bad for your feet, leading to a cocktail recipe of stresses to overload joints, muscles and tendons which work together in complex clockwork action to form a normal step.
Wet the insides of your high heel shoes to stretch them. Water can speed up the breaking in process by helping to mold the inside material of your shoes to your feet. Take a damp cloth and rub the insides of your high heels. Put them on while they’re still moist and wear them for an hour or more. You can also dampen a pair of socks and wear them with your high heels for the same amount of time.
Know your foot type. In my opinion, a podiatrist would be the best way to know your foot type and what’s going on. If you can’t run out to the podiatrist, there’s a couple of neat ways to see if you have a flat foot or a high-arch foot. Wet your foot and step onto a piece of construction paper. When you make an impression, it will show you how much your foot is flattening or how high of an arch you have. You can look at a person’s foot type and see why they are having pain.
