What are OOFOS made of?
OOFOS are constructed from a unique and proprietary, closed cell foam — we named it OOfoam. You won’t find it anywhere but in a pair of OOFOS.
What makes OOfoam special?
When you pick up a pair of OOFOS, the first thing you notice is their incredible lightness. Put them on and you can feel the difference immediately: that’s OOfoam. It’s a breakthrough in recovery technology, offering 37% more impact absorption than EVA (traditional foam found in athletic shoes).
This means that with each step, the impact that travels from your feet up through your body is reduced by more than a third! So instead of stressing tired feet and joints after a workout, OOfoam and the patented OOFOS footbed absorb impact. When you’re not exercising, OOfoam gives your whole body the opportunity to relax, rebuild and recover.
Do OOFOS contain harsh chemicals or dyes?
In designing OOFOS, our first priorities were safety and quality. Unlike cheap flip-flops typically constructed of EVA foam, OOFOS footwear is made using a patented, closed cell foam that has non-toxic properties.  OOFOS are also painted with non-toxic paints.  You can feel good wearing OOFOS next to your skin.
Do OOFOS have latex in them?
No, OOFOS footwear does not contain latex, so those with latex sensitivity can safely wear any of our styles.
Where are OOFOS made?
OOFOS are made in Korea and Vietnam to our closely monitored specifications. The OOmg is made and constructed in China.
How durable are OOFOS?
OOfoam support and cushioning lasts for the life of the shoe. OOFOS don’t lose form as quickly as typical EVA foams. Wear tests show that OOfoam experiences lower abrasion because it moves with the ground and your foot at the same time. It is working “with” hard surfaces rather than against them, which reduces the wear you would see on a normal outsole. We recommend replacing your OOFOS approximately as often as you replace your running shoes, but that is dependent on how often you wear them. We recommend approximately every 4-6 months with regular wear. 
When will the OOMG be available in Men's sizes?
OOFOS expects to launch the OOmg shoe for men in Spring 2018! In the meantime, men’s sizes are two sizes smaller than a woman’s shoe-- for instance a men’s size 9 is a women’s size 11, so you can try the OOmg in women’s sizing. However, we do not consider them unisex, so they have a women’s medium-width footbed and may not fit all men correctly.

Why are OOFOS not “flip flops?”
Traditional flip-flops may offer some comfort, but they lack cushioning and arch support and can actually lead to conditions like tendinitis. Most medical professionals do not recommend wearing flip-flops for this reason — they’re not healthy for your feet. We designed OOFOS to provide impact absorption and arch support typical flip-flops lack, so feet get a chance to recover in between workouts.
What do you mean by “recovery”?
OOFOS was developed by veterans of the athletic footwear industry along with an expert foam chemist. Our mission was to create a new material (OOfoam) that could help fitness enthusiasts and athletes recover in between workouts. Much like sports drinks energy gels help people replenish post-workout, we want OOFOS to be your go-to shoe for taking the stress off feet and joints, so that they can rebuild and recover before tomorrow’s workout.
Can OOFOS really help with recovery?
Yes! The impact absorption properties of OOFOS really do take pressure off of your joints. This allows you to go about your day after a workout without adding unnecessary stress to feet and joints, giving them time to rejuvenate and recharge.
Do I have to be an athlete to wear OOFOS?
Athletes and fitness enthusiasts were the first to recognize how OOFOS made their feet feel better, helping them to recover after a workout. But people who suffer from various foot issues find that the amazing impact absorption properties of OOFOS provide the relief they’re looking for. As well as people just looking for a comfortable, supportive shoe for all day wearing.
Can OOFOS help with my Plantar Fasciitis?
Dating back to the very first wear tests of OOFOS in 2012, many customers have reported relief from pain associated with Plantar Fasciitis and the bone spurs that can accompany this condition. How can that be? Because with OOfoam and our biomechanically engineered footbed help to increase circulation, which in turn helps tissue on the plantar (bottom) of the foot gain mobility, thus taking the pressure off.

But that’s not all — our customers tell us that their neuromas, bunions and hammertoes are also feeling relief as they wear OOFOS.
Are OOFOS good for people with “flat feet”?
Technically, there is no such thing as a flat foot. A foot that is presenting as “flat” is actually a weak foot. Our OOfoam material allows the natural articulation of the foot and engages tissue on the bottom of the foot. The muscles and connective tissue respond to the motion. This activates the muscles in the feet and legs, helping to strengthen them.

You want to make sure the arch of the shoe is centered under the arch of the foot. Next, you want to make sure the heel is fully supported on the footbed. Then you will have the correct fit.

How do I clean my OOFOS?
Keeping your OOFOS looking good as new is easy. You can either toss them in your washing machine on the cold cycle with mild detergent or scrub them in the sink with a brush and mild soap. The OOmg should be washed in cold water on the delicate cycle. Once washed, towel them dry and they’re ready to wear immediately — or put them out to dry in the shade. NEVER put your OOFOS in the dryer.

How do I know what size OOFOS to order?
We have two sizing types of OOFOS-- most of of OOFOS are unisex sizing, medium-width. The OOriginal/ OOriginal Sport, OOahh/OOahh Sport, and OOCloog are all unisex shoes that come in the standard medium width.

Our OOlala collection is a women’s style, medium-width. You will find that the OOlala has a slightly more narrow footbed, and we suggest this style for someone with narrow feet. Our OOmg collection is currently also women’s only, but we will have men’s sizes launching in Spring 2018.

All styles of OOFOS footwear have the same patented footbed design and are made of OOfoam.
If you normally wear a whole size, order the same whole size of OOFOS. Our shoes have a medium-width footbed, but please keep in mind that everyone’s feet are different and the sizing is not the same for everyone.

If you normally wear a half size:
  • Women: we suggest ordering a half size UP for best fit.
  • Men: we suggest ordering a half size DOWN for best fit.
We suggest using our Retail Locator Tool at to find a retail store near you where someone can assist you with fit. Additionally, you can shop worry free at with free shipping!

The footbed of each pair of OOFOS shoes is the same, so the OOCloog should fit the same as other OOFOS. However, some people find that they need to size up in the OOCloog, due to it being closed-toe. Particularly in the colder weather, people tend to wear socks with the clog, as well, so we do recommend sizing up if you are questioning the size.

What is the OOFOS Warranty?
Every pair of OOFOS is under warranty for 6 months from the date of purchase. If it turns out there is a defect in your OOFOS, we will replace them with a new pair. All items returned to OOFOS that have passed the 6 month date of purchase will be evaluated on a case-by-case basis.

Please note that all warranty exchanges will be replaced with the same style, color and size (if unavailable, a pair of the same price will be substituted). Warranty exchanges have a processing time of 7-14 days. Replacement items are shipped via UPS Surepost to addresses in the United States. The warranty covers defective issues as determined by our team, it does not cover excessive wear-and-tear, unauthorized use, or pairs purchased from unauthorized retailers. OOFOS reserves the right to refuse replacement for any reason. If a pair of lesser value is requested, a refund in price difference will not be issued. We do suggest that people who wear OOFOS should inspect them regularly for wear, and replace their OOFOS when excessive wear exists.
