What Custom Orthotics Actually Do (And What They Don’t)

April 22, 2026

Introduction to Custom Orthotics

At Foot & Ankle Associates of Southern NH, located in Derry, New Hampshire, we often receive questions about custom orthotics and their roles in foot health. Many patients are curious about how these devices can alleviate pain and improve mobility, while others are unsure about their limitations. In this blog post, we will explore what custom orthotics actually do and what they don’t, backed by evidence-based research.

What Are Custom Orthotics?

Custom orthotics are specially designed shoe inserts that provide support, alleviate pain, and improve the alignment of the feet and legs. These devices are tailored specifically to the individual’s foot structure based on a thorough examination by a qualified podiatrist. Unlike over-the-counter inserts, custom orthotics offer precise adjustments based on an individual’s specific foot deformities and medical history.

What Conditions Do Custom Orthotics Help Treat?

Custom orthotics are beneficial for a variety of foot and lower limb conditions. Here are some common conditions they help address:

  • Plantar Fasciitis: Inflammation of the plantar fascia can cause heel pain, especially with activity. Custom orthotics help distribute weight evenly across the foot.
  • Flat Feet: Individuals with flat feet often experience pain due to excess strain on the foot’s ligaments. Orthotics provide arch support to relieve discomfort.
  • High Arches: Those with high arches may face instability or pain; orthotics can correct alignment and provide cushioning.
  • Achilles Tendinitis: This condition causes pain at the back of the heel and often benefits from custom arch supports that ease strain on the Achilles tendon.
  • Diabetic Foot Issues: People with diabetes are susceptible to various foot problems. Custom orthotics can prevent ulcers and reduce pressure points.

How Do Custom Orthotics Work?

Custom orthotics function by redistributing forces across the foot. When walking or running, the foot goes through a complex series of movements. Orthotics can:

  • Provide support where it’s specifically needed, preventing excessive motion.
  • Cushion the foot to reduce pressure and absorb shock.
  • Correct alignment issues that may lead to pain in the feet, knees, hips, or back.
  • Enhance overall foot function, which can improve athletic performance.

What Custom Orthotics Don’t Do

While they are an effective treatment option for many conditions, there are limitations to what custom orthotics can accomplish:

  • Not a Cure-All: Custom orthotics do not replace the need for other treatments such as physical therapy or medical interventions.
  • Cannot Correct Structural Deformities: While they can improve function, orthotics will not physically alter the structure of bones or joints.
  • Not Suitable for Everyone: Some individuals may not benefit from custom orthotics and should seek alternative treatments.
  • Require Adjustment Period: It's common for patients to need time to adjust to wearing orthotics. They should not expect immediate relief.

How Can I Get Custom Orthotics?

Receiving custom orthotics typically starts with a consultation. At Foot & Ankle Associates of Southern NH, we use advanced technology to assess your foot structure, motion patterns, and areas of discomfort. Based on this assessment, we will create a tailored orthotic solution ideal for your needs. Follow-up appointments may be necessary to ensure optimal fit and function.

Are Custom Orthotics Covered by Insurance?

Coverage for custom orthotics varies by insurance provider and plan. It’s essential to check with your insurance company to understand your benefits. Many plans do cover custom orthotics when prescribed for specific medical conditions.

FAQs About Custom Orthotics

1. How long does it take to get used to wearing custom orthotics?

Adjustment periods can vary, but many patients require several days to a few weeks to fully adapt to their new orthotics.

2. How often should I replace my custom orthotics?

With proper care, custom orthotics can last 1 to 2 years. However, if you notice deterioration or discomfort, it’s a good idea to have them evaluated.

3. Can I wear custom orthotics in all types of shoes?

While custom orthotics can fit many types of footwear, ensuring they fit well in each shoe is important. They may not be suitable for all shoe styles, particularly those with minimal support.

4. How do I maintain my custom orthotics?

Keep your orthotics clean and dry. Regularly inspect them for wear and tear, and follow any specific care instructions provided by your podiatrist.

5. Are there any side effects from using custom orthotics?

Some patients may initially experience discomfort as they adjust. If persistent pain occurs, consult your podiatrist to ensure your orthotics are correct.
