Those small and soft rounded balls which can be inserted at the end of the shoes are called shoe inserts and they prevent sore in legs. If you have them in high heels they will make it smooth and comfortable for you to walk in them. If you haven’t used shoe inserts yet, give them a try! You will save yourself from the nerve-racking pain of wearing heels.
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.
