HSA/FSA eligible with

Use you HSA/FSA Funds

HSA (Health Savings Account) / FSA (Flexible Spending Account) accounts were created so individuals could use pre-tax money to pay for expenses used to treat, mitigate, or prevent a diagnosed medical condition.

Because HSA/FSAs use pre-tax money, you’re getting more purchasing power for your dollars. Rather than pay taxes on income and then spend it on health items, qualified customers can use pre-tax funds to invest in their health.

Step 1

Ensure you are not signed into “Shop Pay” and don’t use accelerated checkout options (Ex. Shop Pay, Google Pay, Apple Pay).

Step 2

For payment method, choose "Truemed - Pay with HSA/FSA". Truemed is also available under "Alternative Payment Methods"

Payment method selection screen with Visa, Discover, and Truemed options.

More Details

If you pay with your HSA/FSA card, there’s no other work you need to do (we’ll send paperwork to ensure compliance).

If you pay with personal credit card, TrueMed will send reimbursement instructions.

Why Choose FLEX Astra?

Astra

Foot Pain Relief in a Boot

Cute boots and pain relief haven’t always gone hand-in-hand, but they do in this little number. FLEX Astra packs superior arch support, shock absorbing cushion, and our industry-leading KURUSOLE technology, which dynamically flexes to hug and protect the most punished part of the foot: the heel.

Chelsea Goes Flexy

This isn’t just any Chelsea boot. We kept the look but threw out the flat soles and the stiff uppers. Built on the flexible, fan-favorite FLEX Via sneaker base, FLEX Astra may just make you forget you’re wearing shoes.

Exits Made Easy

Get out the door quickly with this boot’s chic, stretchy side panels, heel pull tabs, and soft leather uppers. Just one more way FLEX Astra makes it simpler to live the life you love.

Astra

A Groovy Foundation

No heavy steps here. FLEX Astra’s grooved design keeps you light on your feet and rolling through each step with ease.

Chilly Season Staple

This classic Chelsea style features neutral full-grain leather uppers that are the perfect match for any fall or winter outfit.

Tech with

Hugs that Heal

Comfort. Support. Relief. All in one shoe! Unlike anything else, our patented KURUSOLE cradles your heels, protecting your body's natural cushioning while boosting ankle stability and arch support. Providing adaptive support that protects what matters most with every step.

Technology

Designed for Life

Every KURU features shock-absorbing KURUCLOUD for all-day energy, heel-hugging KURUSOLE for healthier joints, arch-supporting ULTIMATE INSOLES for a custom fit, and generous toe boxes so your feet can spread out naturally.
