Bend and twist them. You can work out the stiffness of your new heels by bending and twisting them. Apply slight pressure as you bend the shoes upwards and downwards and twist them side to side. Don’t do either method too hard or too quickly. You don’t want to force the shoe into a position that it shouldn’t be making. Doing so could damage the shoe or weaken it in places that should remain sturdy.
This secret to reduce pain while wearing heels is so good, you’re going to want to share it. Woman’s Wear Daily recommends taping your third and fourth toes (counting from the big toe) together to alleviate pain from wearing high heels. Sound crazy? The proof is in the science: there’s a nerve that splits between those two toes, which causes pain when pressure is put on it (like when you wear heels). The tape helps to remove strain on the nerve. 
Keep silica gel packets in your shoes when they’re not being worn.[3] 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.
