"I was diagnosed with metatarsalgia. Finally, last summer I decided to give custom orthotics a try. I appreciated the guarantee. I have absolutely loved my orthotics! I wear them in my exercise shoes, and exercise without pain during and after. They have been a Godsend. Absolutely worth the cost."

"I was a professional track athlete for many years and I competed in the 800 meters starting from a young age. I have always required orthotics and I can say that your product is a perfect 10! The price is reasonable and the quality is awesome. I would recommend your orthotics to all!"

"The measurement and order process was simplicity itself. First an impression kit arrived with a return shipping label. The custom made insole sent to me a little while after the return of the impression kit. It appears a nicely done, well made item, that helps a lot in my everyday walking."

FSA Questions

Common questions about using your benefits for custom insoles.

Are orthotics covered by FSA?
Yes. Because Bilt Labs orthotics are custom-molded medical devices used to treat specific foot conditions (like plantar fasciitis or flat feet), they are fully eligible for purchase with your Flexible Spending Account (FSA).
Are foot inserts FSA eligible?
Yes, specifically if they are designed to treat a medical condition. Bilt Labs custom foot inserts are manufactured to correct biomechanical issues, making them a qualified medical expense for FSA funds.
How do I checkout with my FSA card?
It's simple. Select "Credit Card" at checkout and enter your FSA card information just like a standard Visa or Mastercard. Our system is coded to accept benefits cards directly.
Do I need a doctor's prescription?
No prior visit is required. Our Chief Medical Officer, Dr. William Naughton, oversees our lab protocols. The specific medical necessity is established through your custom impression and analysis, allowing us to fabricate a medical device for you directly.
How do I get a receipt for reimbursement?
After your purchase, you will receive a detailed itemized receipt via email. This document contains all the necessary information your benefits administrator requires to verify the medical expense.
Are custom insoles worth the investment?
Yes. Using pre-tax funds for custom insoles is one of the best ways to maximize your benefits. Unlike single-use medical supplies, our orthotics last for years, providing long-term structural correction and daily pain relief.
