Flux Footwear is now FSA & HSA Eligible!

At Flux, we believe that access to natural movement footwear should be simple which is why we've partnered with Truemed. Truemed allows you to use your Flexible Spending Account (FSA) or your Health Savings Account (HSA) towards your footwear purchase.

FAQs

If you'd like to get qualified during checkout, please do the following:

  • Add your Flux to cart
  • Check out as a guest to ensure the TrueMed payment option appears (do not use Shop Pay or Apple Pay)
  • Fill out your details and shipping information
  • On the payment screen, select Truemed as the payment method and enter your FSA/HSA debit card information or check out with a normal credit card.
  • Complete the intake form to assess your eligibility.
  • If qualified, you will receive your Letter of Medical Necessity from TrueMed within 24 hours.

Truemed will provide a Letter of Medical Necessity via email within 24 hours after purchase.

Each Letter of Medical Necessity can cover multiple footwear products from Flux.

Each Letter is valid for 12 months before it needs to be renewed.

Eligibility of reimbursement claims for previous orders is subject to requirements set forth by your FSA/HSA provider so we recommend contacting them for inquires related to reimbursement for previous orders.

Most FSA and HSA administrators approve these expenses within days of when you submit. The exact timing will depend on your specific administrator.

If you do not have enough funds on your HSA/FSA card, you can use the pay with credit card option on the TrueMed portal when checking out. You can then submit your purchase for partial reimbursement with your provider. Your administrator can then reimburse you with whatever remaining balance you have in your account if it less than the purchase price.

Only footwear purchases will be FSA/HSA eligible. Accessories are not considered eligible.
