Before you buy a new pair of shoes or toss the ones you just bought, consider all of the shoe and boot problems that a cobbler can fix. DIY alternatives: Wear your shoes or boots around the house with your thickest socks. Or, place a bag of water inside the footbed of a pair of shoes or boots and place them in the freezer. When the water freezes, it will stretch out the shoe. Also as a preventative, cobblers can place a heel tip over your existing one so it doesn’t wear out as quickly.
