Reviews

Favorite Shoe

"I love this shoe. I wear it now everyday to work. I am in sales and my comfort is #1 priority. I have now purchased 6 pairs of Oofos in the last month, including 2 pairs of Zen"

— David M. (5/5)

Great shoes, but heads up re: sizing

"I like these shoes, but the sizing is different from my prior Oofos slip-on shoes. I wear Oofos as house slippers since I work from home. In the others I was a size 8.5. 8.5 was too big in this style so I ordered these in an 8, then a 7.5. The 8 was good for the length but the stretchy upper is really loose and probably a better fit for a wider foot. I ordered the 7.5 to check them out and while the upper was a better fit, they were just a bit too short. I kept the 8 and I like them well enough, but they feel so much looser than my prior Oofos, which I preferred."

— Heather (4/5)

Based day one wear

"I like them - very cushion-y! Just a little looser fit than I prefer. And they "look big. " But I'll be able to wear them with socks. And after all day wear (sitting, standing, walking over variety of surfaces, driving) my feet feel less tired at the end of the day than other shoes. Might try insoles to adjust fit. I like them enough to not give up (or return) on them."

Buy These!

"As someone who is frequently on their feet in an OR, these shoes are a blessing. My first day owning them, I wore them fresh out of the box for a 13 mile walk around NYC. I've worn them at work every single day since. They wash and dry perfectly without changing how they feel on the feet or their overall general shape. I don't think about my feet anymore while working and that alone is a miracle. Knees and back feel better too! 10/10 recommend!"

— Lauren R. (5/5)

1day review

"So far they have been comfortable. Definitely size up! My negative would be the construction. There is what looks like white glue all around the shoe top where it meets the sole. Needless to say I won't be showing people my shoes if this is the quality to expect."

— Rhoda M. (3/5)

Best Oofos sneaker ever!

"The Zen are the most amazing shoes. Please don't ever stop making this style! I'd love to see other colors in the women's sizes, such as navy, teal, olive, tan. . . . This is the most comfortable slip-on sneaker that gives arch support and heel cushioning. Such a relief for my plantar fascitis and neuroma. I absolutely love this shoe and have it in 4 colors. I love the easy slip on and the wide toe box and the boost of height with the low platform. I wear a 8. 5 in dress shoes and I ordered this in a 9 and it fits perfectly with enough room to wear socks."

— Sara (5/5)

Comfy but slick

"Shoe is comfortable. I sized up a half size and that was a good idea. Shoe has little tread, slick on some floors. Band around ankle is tight on me, I do have wide ankles though."

— Teddi C. (3/5)

Wow, Just WOW,

"My feet starting hurting this year. I purchased Oofos sandals and my feet starting feeling much better. But needed shoes for walking around to do errands and such. These are so amazing, I have no pain at all and am walking like normal without any issues at all. I cannot believe how great these shoes are, or how much they have helped me get back to walking around! Shoes are so comfortable and honestly the best shoes I have ever worn!"

— L. B. (5/5)

Remains to be seen

"I bought these reluctantly. I’ve worn the Oofos brand for a few years now and it’s the only one I’ll wear to work where I’m on my feet all day. However, they recently stopped making the Oomg Sport Low shoe and now I have to find a substitute. I don’t love this shoe - it’s bulky - but it’s my only choice. Perhaps this shoe will be “good enough” but I really hope the low shoes comes back."

— Andrea L. (2/5)

Wish all-black NON SLIP was available

"It's not as important to me now that I have switched careers, but when I was in the service industry doing over 20k steps a day, I would have given my left arm to have a pair of OOFOS that were all black and NON SLIP. There are not a lot of competitors on the market at the time I'm writing this; I used a $200 pair of HOKA non slips with $500 inserts did all the physical therapy and stretches regularly, etc. When I went back to the podiatrist a year later, she said my PF had only gotten worse. OOFOS are some of the only shoes that bring me comfort, and I wish I had enough pairs to wear a new one every day of the week, in addition to some that I could wear on special occasions."

— Lauren (4/5)
