Hunter boots do not stretch over-time like any other boots, but there are some techniques by which you can extend your Hunter boots slightly. First, tart wearing and walking on your boots daily; what it will do is change the boot’s shape slightly. Take a bag of water and put it inside the shoes and keep them in the freezer. Freezing expands the water and forces the boots to hold the shape and stretch. Spraying shoe stretching liquid on your boots will help it to alter the shape of your foot. Cobbler to the rescue. Take your shoes to the cobbler; as they are professional, they can correctly stretch your Hunter boots.
