If you're pounding the pavement and walking a lot in your high heels, try wearing an insert. Dr. Scholl's is well known for their shoe comfort accessories. This brand has a vast array of inserts and pads that you can purchase at almost any drug store, including some for the sole of the shoe, cushion for the ball, and even a barrier between the back of the shoe and your heel. Try the Stylish Step High Heel Relief Insoles in your favorite pair of heels for a dose of comfort.
There's a nerve that splits between your third and fourth toes that causes pain when pressure is put on it. To relieve some of that stress on your poor little toes, tape your third and fourth toes together (your big toe is #1) with some medical tape or a band aid. Obviously, this trick only works with closed-toed shoes where your third and fourth toes aren't exposed.
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.
