Great product!

The media could not be loaded. Update: They removed the venting holes which are particularly important to me since I distant run. I would have thought it was a mistake but I ordered two pairs in different sizes be the venting holes are missing from both. That’s disappointing especially since there was no indication that they made a design change.Original ReviewI’m a distance runner (on and off since 1989). Over the past year I started having sharp knee pains when running and then when walking. So I stopped running, but I could not stop walking. The pain occurred frequently, almost every time I walked. Also I had a trip planned to Spain where I would be walking many miles. After a lot of research I found these inserts for low arch/flat feet. They arrived days before my trip and I started using them immediately. The first walk I had zero knee pain and I was cautiously optimistic. I wore them in Spain and walked many miles (approximately 30) with zero knee pain. Thank God!! They really work! I wore three different pairs or shoes swapping the inserts each time. I’ll be ordering several more because I wear various work, casual and athletic shoes. By the way, I’ve been switching these inserts between my sneakers, oxfords, and casual footwear and they fit perfectly and work in each style. I’m truly impressed and so happy. Now I can begin training for my next race. One note about comfort, they are noticeable because they provide support where your foot needs it. Some may find this uncomfortable at times. No knee pain far outweighs the feeling of the artificial arch support. I’ve already gotten used to the feeling of the new support. They have a new customer for sure.

Superfeet changed the design of this insole (no more holes) and the new insoles were squeaking in my new Adidas Kaptirs. I found that the squeaking stopped when I sprinkled some baby powder on the rubbing surfaces.

Helped a ton with foot confirmation, support snd knee pain while distance running.

I've used three different Superfeet insoles. In my hiking boots I have the hike support and those are great. In my converse I've removed the insole and tried both the Carbon (these) and the Flexthin.The Carbon and Flexthin are pretty similar in how they fit in the shoe. However, Carbon is a very rigid heel and the design of it basically has a ball on the heel. It feels like you're walking on hard plastic. The shape of the heel makes the heel not very stable so you feel a bit wobbly.Now I'm not running in these shoes - probably if I was always in motion the wobbly aspect wouldn't be so pronounced. And the comfort of this sort of thing is going to vary from foot and shoe. But, given just how rigid these things are and the shape I would expect them to be less forgiving as compared to other options. With the right foot in the right shoe they're probably better and more supportive while still being a very thin profile. They just weren't for me.

If you have flat feet, you MUST use an insole that has a lower arch support. Do NOT get an insole with arches that push up too high or else you will experience pain. About 10+ years ago, folks said the flatter your arch, the higher the arch support in the insole. But now, it's the opposite. And believe it or not, if you have flat fleet, it isn't really about arch support but it's more about overall foot stability. And insoles with a nice heel cup will provide that.In regards to the Superfeet Carbon, I love them. I switched from Powerstep insoles to these. While Powerstep has provided me the support I needed since 2002, it's now to use insoles with a lower arch support for my flat feet and I have to say, I noticed difference the first day. While I was able to run in Powersteps, the arch I thought was always too high. While the Powersteps eliminated shin splints and knee pain, my feet sometimes would experience an awkward pain towards the far outside edges and this make sense since the Powersteps pushes my arch higher and therefore distributing more weight towards the outside of my feet. With the Carbons, the arch support is lower but it's still there. The key is the heel cup. The support the heel cup provides is absolutely the best and while it keeps my heel locked in, the insole reinforces my entire foot to work as it should with minimal to no roll in the heel section.If you play sports, run or do a lot of walking and you have flat feet, please get these. It's the best $50 you'll ever spend. I currently own one and I plan on purchasing my 2nd and 3rd pair.

When my Physical therapist suggested I get some inserts to help in correcting my patellar tendonitis, I was skeptical.I do have flat feet and the arches collapse even more when my feet get tired from a long run, jumping rope, or a hard workout.These are indeed very light and very rigid without feeling uncomfortably high.They are indeed really thin so they were easy to add on top of sneakers that didn't have a removable insole without adding too much bulk or height to the shoe. My Asics I use for running had removable insoles of nearly the same thickness so they were a perfect match. I also used them in my Puma indoor soccer shoes as well as Nike trainers and running shoes. Comfortable and stable in everything.The logos peel off the top of them pretty fast from hard use... But they don't really change how they work or feel.They made me Much more aware of when my feet were starting to get tired. They continued to give me support even when they were tired and wanted to collapse causing my alignment issues and aggravating my knee tendonitis.Unfortunately, these are NOT thin enough for dance shoes. I wish there was something on the market that has dancers in mind... Allowing for feel in the toes and mobility in the balls of the feet while still providing arch support. They would have to be even thinner than these.I also wish they were cheaper so I could get more sets instead of swapping!
