Just pure, peaceful relief with every step.

Reviews

Great shoes

"I bought a pair of sandals in Hawaii three years ago. Very impressed with them. Earlier this year (2026) we went back. My Plantar Faciitis was acting up, so I wore the sandals almost all the time. They really helped. When we got back, I checked out their website. I bought several pairs, from the cloggs to the dressy ones and wear them all the time. I plan on getting a few more, including the slippers."

— David A. (5/5)

OOMy Zen response

"I like the way these shoes feel on my feet when wearing socks. I like the feel of walking in them. I like the way they look on my feet. The only issue I have is the size of the opening. It is pretty small. It is difficult to get them on my size 12 D feet. The top (the opening) is a bit irritating if I am not wearing socks with them."

— Earl S. (4/5)

Gave me my life back

"These shoes are amazing and have given me my life back in a sense. I couldn’t even stand in the kitchen to make dinner - now I can stand on hard surfaces all day. I can go for hikes again, I can play with my kids again. I was at a point in my life - early 40’s where I felt like a cripple and could go enjoy time with my family - these shoes have saved me. Unbelievable and worth every penny"

— Robert D. (5/5)

Makes my back bearable

"I have an indoor pair and outdoor pair. Without them standing or walking for 45 minutes I’m done - I can go all day in these shoes. They have given me my life back in a sense as I can do the things I enjoy again. Even in the kitchen cooking was impossible - I can cook and make meals again for my family - going on hikes was impossible and now I can go again."

— Robert D. (5/5)

Life changing

"I ordered some slides 5 years ago. I've had 2 back surgeries, a hip replacement and a knee replacement. The minute I put the Oofos on the pain and pressure in my hips and knees was incredibly better. I only where Oofos, I now own 8 pair, between slides and everyday shoes and clogs. Thank you Oofos"

— Adam P. (5/5)

Most comfortable shoe ever!

"I love my new Zen shoes! The foliage is the perfect color for me and this is the second pair of OOFOS I've purchased. They feel like walking on clouds. I will definitely be purchasing more in the future. Can't recommend these enough."

— Michael P. (5/5)

relief of plantar fasciitis

"I now own 5 different pairs of oofos. Recently I developed plantar fasciitis in my right foot. Most likely from a worn pair of FJ golf shoes. I found that wearing oofos prior and post golf rounds eases the pain. In fact I now also own a pair of the FJ/oofos collaboration slides which I wear immediately following a round of golf. I recommend these to everyone I know as well as my golf buddies. I would like to see a pair oofos golf shoes on the market, as even a premium pair of $250 golf shoes are not very comfortable with an insert. Please present my suggestion to your R&D and product development staff."

— Michael O. (5/5)

Durability of sole

"Love the fit and comfort, but after just a few months of walking, the sole beneath the ball of the foot is deteriorating significantly."

— Dale D. (3/5)

Outstanding comfort and ankle support.

"A little tight slipping on, but once they are on…. I do not want to take the off. Truly great bottom foot support I needed and I really enjoy the ankle steadfastness. Great job again Oofos!"

— Raymond D. (5/5)

Disappointed

"First pair…ordered my usual size 12 (although my best fit in walking shoes is 12EE), and they are extremely difficult to get on, especially the left one. I planned to use them as recovery shoes and casual wear shoes."

— Herbert H. (3/5)
