Which OOFOS footwear is eligible for HSA & FSA payment with Flex?

Why can't I see Flex as a payment method?

Reviews

Adjustment Aches

"My heel doesn't hurt anymore, but now my inner arch, my toes, and the ball of my foot do. I read that sometimes that can happen if you have flat feet and go from not wearing these at all to wearing them basically all day. If it feels like your toes are dangling in the air when you wear these, you might be in the same boat. If so, I'd recommend wearing them with thick socks or just taking breaks."

— Chris C. (4/5)

Love my slippers!

"I got a great deal on these during the summer clearance sale… Maybe because neon orange with lime green insoles didn’t appeal to everybody. I find them absolutely perfect for kicking around the house; they’re the most comfortable slippers I own."

— Dave B. (5/5)

Wrapped in Comfory

"A friend introduced me to these and I liked the style immediately. I read online reviews and was concerned they would be too warm for a house slipper. Ultimately, I placed the order and they are perfect. Comfortable. Attractive. Warm."

— David T. (5/5)

Comfortable but over priced!

"I’d wear them inside or outside in the fall/winter timeframe."

— Perry R. (3/5)

I like them very much.

"The arch support, which is very important to me, is very good. To be honest, there was a brief adjustment period; I wasn't used to slippers without tall backs. The only complaint I have is that they squeak, loudly, with each step."

— Christopher D. (5/5)

Runs very large

"Nice shoe, just runs very big."

— Kenneth B. (2/5)

Love it

"I love it and it is very comfortable but it is wide a little still very good"

— FARIS A. (4/5)

oOFOS

"I love OOFOS! I have 7 pairs now The most comfortable shoe I ever put on my feet. I wish they had the clogs in my size."

— Terral S. (5/5)

Perfect!

"Oofos plus warmth. the perfect combination. Around the house, cabin and after mountain activities. Just perfect."

— Chris (5/5)

Best slipper and quick run out to store too shoes

"Love the comfort and that they are a little wide and soft on the top of foot no rubbing"
