One thing to try are the over-the-counter products that market themselves for high heels. They are called metatarsal or ball of the foot pads. They are oval-shaped pads that go under the ball of the foot, usually made from a silicone gel. They combat soreness under the ball of the foot. Especially if it’s made of silicone, it will hold your foot more steady in the shoe so your feet aren’t sliding forward as much, which will protect your toes from friction and blisters.
3. Widen the toes out with ice. When water freezes, it expands. Use this simple science lesson to stretch out your shoes. Start by filling a one-quart sized ziplock bag about halfway full of water. Then, zip up the bag and check to make sure it’s not leaking. Stick the water bag into the toe of the heel and put the entire shoe in the freezer. If you really need to stretch them out, add two or more bags into the toe box. Once frozen, the bags will expand and the shoe.
Size and shape: When was the last time you had your foot measured? If you’ve had children/gained or lost weight/or just plain can’t remember, it’s time for a recheck. Too small and your foot doesn’t sit well in the arch. Too big and it slides forward. The best fit will nicely hug and support your arch, and it definitely shouldn't hurt. Also, opt for wider toe boxes for best comfort and less long-term injury.
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.
