You need to take regular intervals to save you from the pain of wearing heels, no matter how good the quality of your heels is. You need to bring out your legs from the heeled shoes once in a while. You can take regular breaks after every 30 minutes if you suffer from severe pain because the breaks will let your feet breathe and shoo away the pain.
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.
