Yes. Every Footwear product in the Flex Marketplace is HSA/FSA eligible, though some require a Letter of Medical Necessity (LMN) before you can spend pre-tax dollars on them. If one does, Flex walks you through a brief chat-based consultation at checkout to confirm eligibility. You can pay with your HSA/FSA card, split the payment with a credit or debit card, or pay in full and submit the itemized receipt Flex sends you for reimbursement.

At checkout, select "Flex | Pay with HSA/FSA." Some products require a Letter of Medical Necessity. Complete a brief chat-based telehealth consultation to confirm eligibility if required. Enter your HSA/FSA card details and complete your purchase. If you don’t have your HSA/FSA card available, use a regular credit or debit card. Submit your Letter of Medical Necessity and itemized receipt (provided by Flex) to your HSA/FSA administrator for reimbursement.

HSA and FSA cards are debit cards, and the most common reason for declines is insufficient funds. Reach out to your HSA/FSA administrator to confirm your balance.

If you don’t have your HSA or FSA card handy, still select “Flex - Pay with HSA/FSA” as your payment method. Enter your credit card information and Flex will email you an itemized receipt to submit for reimbursement.

All products shown in the Flex Marketplace are HSA/FSA eligible, some may require a Letter of Medical Necessity (LMN). Some brands may also offer additional eligible items on their website.
