"These were too small. The thick sole was not as comfortable as I thought it would be. Last week I initiated a return amd am still waiting to receive my confirmation email and shipping label. Why does it need to take "3-5 business days" to review my return?"
"Got a pair of slippers and slides after my dad and sister told me how much they love them. I have noticed less pain when i am on my feet more when wearing these shoes."
"I love these shoes. These shoes are super comfortable and I wear them everywhere. Shipping was super quick also. I have two pairs now and nothing about them has any negative. They are also very easy to clean."
"You are incredible! Despite the fact that they’re white, it look like nursing shoes, they are the most incredibly comfortable I’ve ever owned. The fabric is soft and slightly stretchy… Fits, amazingly, slightly loose, but great fit still. Foot bed is soft and comfortable, not squishy not hard, the perfect just in between."
"Very comfortable, but they REALLY don't wear well. Notice the wear in the attached photo--both on the top of the shoe near my heel and on the tread. These were a Christmas gift in 2025. . . so they are just barely 4 months old. And I am a 77 year old retired woman, so not exactly giving them hard usage. For the price, they should have lasted a LOT longer."
"I bought these to use as slippers, which I wear every day in our house. These are so comfortable! The only negative thing about them is when I put these on, I can slide my fingers inside the top of the mule onto the top of my foot, down towards my toes. . . my foot is fairly narrow and I have this problem with some shoes, most flip flops and slippers. That's why I said they are too wide. . . just a little though. I do believe these will stay on my feet much better than the thinner fuzzy mules that OOFOS discontinued. That material stretched out over time after wearing and I did my fair share of tripping over them. Even though I said they are too wide, I still gave them 5 stars because I absolutely love them. Since most of my family and friends have "normal" feet, I will recommend these slippers to them."
"OOFOS were recommended to assist with pain relief from plantar fasciitis. From the moment I put them on my pain was alleviated. Now I wear the slippers or the clogs (which I purchased first) all day when I can. To my great relief they have also helped with back pain. It’s not an exaggeration to say they have been life changing. I’m now able to wear my other shoes for short periods without pain. Please develop boots that can be worn in the winter as well!"
"I bought these to use as a house shoe after developing horrible foot pain in pregnancy. I stay home with my other kids and am on my feet all day. These shoes are super comfortable and have helped so much! My only complaint is they are very warm-- it would be awesome if they could make the upper part of the shoe a more breathable material. They are also not cute but the comfort it worth it for me :)"
"These new slippers do not have an adequate grip on the bottom and I slipped and fell on the hardwood floor of my bedroom. The orthopedist said I have a contusion of my right shoulder and knee. The shoulder is still very painful. I will be returning the slippers."
"I love how lightweight it is when I'm traveling; the older I get, the less I want to carry a bunch of weight around. Can't beat the comfort of this shoe either."
