Reviews

Great Shoe

"I use this shoe as my going out shoe. It works as I need it for most things and is very comfortable. Amazingly good fit for me, especially given it is a no lace shoe. Only downsides I notice are that they wear out within a year of daily use and that these ones show dirt very clearly so I have to clean very frequently if I want to keep them looking clean."

— Joseph H. (5/5)

Great. shoes, great price!

"Theses shoes offer great support with my low back issues a well as planter facetious. Not too picky about colors I look for great sale prices. But when these showed up I liked the color and the style too. They seem even more supportive then previous versions,"

— Rick G. (5/5)

Worst shoes ever

"I love OOFOS Slides. First time trying their shoes and definitely the last. Either I have strange shaped feet (doubtful as I'm 75 and have never experienced this problem) or they don't know how to build proper arch support in their shoes. The arch support is way at the back of the arch, almost to the heel, and it goes across the entire shoe, so it feels like I'm walking with a bar across the shoe."

— Duke W. (1/5)

I love my oofos slides

"I love my oofos slides but I believe there are issues with the footbed of this shoe. The first pair i received were readily replaced when I noted a large crease in one of the footbeds that made wearing them uncomfortable. Thanks customer service!!! The second pair both had creases in the footbeds that were not as uncomfortable but still noticeable. I would have asked for a refund but it was final sale so I'll see if i can get a thin footbed to put in. The sizing was spot on, a little tight around the ankle but maybe that will stretch over time. To be honest, i haven't worn them much because of the creases :("

— Jim R. (1/5)

Real recovery

"I had a bad case of plantar fasciitis. Both feet but especially bad in my left foot. I've always treated myself to nice shoes and promptly got myself several pairs of Hoka shoes. The Hoka shoes felt good on my feet but did not help the awful pain of plantar fasciitis. I saw Oofos on social media and bought a pair out of desperation not really thinking they would make a difference. . . After a few weeks of wearing the Oofos I noticed a decrease in pain and after about two months the plantar fasciitis was gone. I now have several pairs of Oofo shoes, slides, and flip-flops. I am grateful for the excellent quality and the real recovery your shoes provided me. Thank you. My plantar fasciitis is gone. I have donated my Hoka shoes as they just aren't as good as my Oofos and my feet have zero pain!!!"

— Thomas L. (5/5)

Oofos for stability

"I love my Ooofos clogs, easy to slide into and comfortable fit. But I found them hazardous at times, especially when wet, for the same reason, easy to slide out of. Almost twisted my ankle a couple of times. Realized as an active senior maybe not the best for me. The slip on shoe style is comfortable and stays on and keeps my foot in so I won’t risk falling. I’m taking them on a cycling trip where I need to pack light, I think they will be perfect for after the rides in camp."

— Pat D. (5/5)

Extremely comfortable!

"I have a pair of OOFOS slides and pair of OOFOS sandals that were recommended by my Podiatrist for indoor wear. I hadn’t really thought of OOFOS for outdoor wear, but I absolutely love my new Zen Slip-On’s. They are extremely comfortable and so easy to put on and take off. I’m happy I finally discovered these slip-on’s."

— Luis B. (5/5)

Big fan of my oofos

"Big fan of my oofos zens for just meandering around the house and going to the gym. Catching them on sale was a bonus. My boots were making my 50 year old feet ache. These shoes are great for recovery time and weekends."

— jprs883 (5/5)

OOmy

"I love these new shoes. I had to have something to fix easy because I had a total knee replacement surgery. Thank you so much! Also the tie up grey shoes that I ordered are a little too wide and 1/2 size too big. Could you please send me the 11 1/2 in those."

— Phyllis C. (5/5)

Buy mens for the width

"I stand all day for my job. I buy mens shoes for the width. These shoes are perfect because they have a slight arch to help with balance, a very cushioned sole and insole, and shaped perfectly for wide feet. Great toe room. Please please please make the womens shoes with a 'wide' option."

— Donna G. (5/5)
