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.
The No. 1 mistake women likely make is not having the right shoe size for their foot. Your foot size changes over the years, even as much as one full size, especially after having kids. Have your feet sized once a year, and do it if you’ve never had it done. Have your feet measured when you’re buying shoes, for width and for length as well. A lot of people think they’re a wide or vise versa and they’re not, so definitely do that before you shop.
Keep silica gel packets in your shoes when they’re not being worn. Have you noticed after purchasing a pair of new shoes those little white packets containing tiny clear balls inside your shoe box? Those packets contain silica gel which absorb moisture and keep your shoes from shrinking. Hold on to those packets instead of throwing them away and stick them in your shoes when you’re not wearing them. You can ask a shoe store associate for extras, if necessary.
