Find a pair of shoes you’d like to wear your insoles in, remove their stock insoles and replace them with your Fultons. They’re ready to be worn! Start by walking in them to mold the insoles to your feet and your shoes. The break in period should take about 10 hours of walking, and by the end, your insoles should feel naturally molded to your feet and shoes - therefore, it’s best to keep them in one pair of shoes.
If you want help understanding which shoes work best with your Fulton insoles, refer to the compatibility chart for the Classic Insoles here and the Athletic Insoles here.
