You can easily cut these insoles to fit your shoes. Check whether your shoes already have an insole and if so, take them out. Place the insoles in your shoes to see how they fit and cut them according to your shoe size. Use the outline on the bottom of the insoles, near the toes. Make sure the insert lies flat. If not, trim a little more if necessary.
The arch supports fit most shoes, such as boots, flats and sneakers. They also fit into high-heeled shoes, but we don't recommend you wear high heels often if you already suffer from foot pain. High heels can worsen foot problems because they put the foot in an awkward position. Make sure that all shoes have enough space for the insoles and that your foot sits comfortably.
