Reviews

Best shoes

"I packed a pair of these shoes for a vacation that would involve a lot of walking (I average 14,000 steps per day) and they exceeded my expectations. No foot pain, perfect fit and I ordered a second pair when I arrived home. The first pair will now replace my regular outdoor walking shoes as part of my daily workout. I always loved the slides (4 year customer) and this is the first pair of closed shoes I bought. Thank you OOFOS!"

— Rebecca (5/5)

Tsaturn

"Thanks! I finally got the most comfortable working shoes for work! I tried all the brands...OC, Hooks, Brooks..every brand and finally I m healed from aches after working qqhours shift. Thank you again and of course ill be ordering more in the future."

— Teresita S. (5/5)

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)

Finally comfort on the bottom of my feet

"I have horrible feet. Everything is wrong with them from neuropathy to plantar facitius, to corns to bunions. These are great shoes for dog walking which is why I bought them. The round toe gives my pinched toes room - like walking in a cloud"

— Jennifer L. (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)

Only shoes I wear

"Wearing Oofos for years, too many clogs and slides to count. these shoes are the greatest ever. I badly NEED these in more colors AND a red carpet option in case I have to go to a wedding or event, cause I will not wear heels or dress shoes under ANY circumstances. Too old, feet hurt too much. I will bedazzle them if I must. But seriously, think about the red carpet option. Def more colors!"

— Tee (5/5)

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."

— wandaworx (3/5)

Awesome

"These sneakers are the best! I bought them cause I was going on a trip where there was going to be a lot of walking all day. OMG! I should have bought them long time ago. The best."

— estylauder63 M. (5/5)

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)
