Reviews

Great slipons

"I bought the first pair for work purpose. I work in medical field and on my foot almost all day and I have plantar faciaitis. I needed a really comfortable one and didn't want to spend $150 on a hokas for work. I gave this one a try and wow it is really comfortable. I ended up getting two more pairs, one for personal use and one for back up for work later on. The only thing was I went half size down based on Google size review because it said oofos run a little bigger in size than your regular one, but it was little tight. The second and third pair I got my usual size which is 10 1/2 and it was perfect fit. So get your usual size. I highly recommend oofos. They just became my favorite brand."

Can’t beat them

"I’m a teacher so I am on my feet a lot. I am also an EMS worker part time so I stay busy. I have not put on a pair of shoes that are as comfortable as OOFOS. I would own at least 2 more pairs if I could because they are that good. I’ve recommended them to everyone I work with as a way to help their feet feel good."

— Connor M. (5/5)

Terrible shoes. Can’t get my

"Terrible shoes. Can’t get my feet in to the shoe. Back of shoe collapses. A shoe horn doesn’t help. I didn’t kniw about the no return policy on final sales. Would never buy online again."

— Ronald B. (1/5)

It’s a good looking sneaker, but…

"I took a chance on a pair of sneakers that were on final sale. I’m a size 13. All my shoes are 13s. I ordered size 13. The sneakers that I received from oofos are small on my size 13 feet. I called the company and explained that these shoes are too small. They reminded me that it was a final sale, no refund or return. If anyone out there with size 12 feet, call me! I have a nice pair of sneakers for you!"

Unfortunately my first and last

"Unfortunately my first and last OOFOS purchase. They are definitely not very comfortable compared to On Cloud’s. Two stars for the nice color."

— henry g. (2/5)

Love the shoes

"I have a lot of back/hip and knee conditions and standing for long periods of time are horrible for me but these shoes have helped me a lot , I’m still in pain but the level of it has changed so much I have 3 pairs now , hopefully I’ll get the black on black one day"

— ryan H. (5/5)

Good shoes but a bit tight

"Shoes are great, provides good comfort and pain relief. However, the no lace part makes it very tight on top. Overall good pair of shoes just wish it was more adjustable on top."

— Chi L. (4/5)

So comfortable

"I had pain in my left foot, AI recommended Hoka to relieve the pain. My job requires walking and standing for 10 hours a day. Hoka relieved my pain in left foot, but caused plantar fasciitis in my right foot. Oofas has been great, no left foot pain, and plantar fasciitis is slowly improving on the right foot"

— LLEW C. (5/5)

Strangles my angles. too tight thru the middle

"i ordered online, the only pair in my price range. same size as other shoe brands that use CM.. the ankle opening is far far far too tight to be comfortable and the middle of the shoe on the top of the foot is also way to tight to be comforably worn. I did not realize i could not return them. So i paid about $50 to find out the fit is terrible for me. 5'11" 192lb. Never had a problem buying shoes like this before and I am nearly 72 years old. Then try talking to a human being at this operation. Nothing but AI slop."

STRONG and DURABLE

"The Men's OOmy Zen are AMAZING!!!!!! I am a school teacher and constantly on my feet all day. I used to wear just regular tennis shoes but my feet would ache after a long day at school. But not anymore! I'm able to go home, then hit the gym getting a good workout!"
