Orthotics are created so that by wearing them, you’re providing stability and balance to an otherwise asymmetrical body. None of us are perfectly symmetrical; therefore, any activity without any support can magnify any imbalances in your feet and limbs by causing unnecessary strain and pain. The most common reasons people use foot orthoses are for arch and heel pain, such as plantar fasciitis, lower leg tendonitis, and knee pain, such as runner’s knee. Whether you have weak arches, or they are very high or quite low, orthotics can balance them and ease any strain. Orthotics can also ease the impact felt on your knees and ankles.
