This product is very innovative. I assumed it was an insole that went directly into the shoe like most others. What makes this insole unique is that it one goes underneath the shoe insert and the carbon has certain properties to help the feet without actual contact. I like this aspect and believe with time and wearing them the benefit will surely become more apparent. The thing I didn’t like was that they were very rigid as it is something I didn’t expect. When I first opened it up I saw that it was very thin too but of course, it has to be for it to be added under the insole. All and all it is a very well made product and I’m sure there are some benefits to be reaped with wearing them. If this product is what you are looking for then this one is recommended and certainly worth a try! Read more

I’m amazed at the strength of these carbon fiber insoles. They are incredibly stiff (you can bend them, but you have to work at it) despite their thinness. I’ve been having some pain behind my toes when I walk, and the doctor told me it was because I was bending my toes too much and irritating the joints behind them. He told me that he could do several invasive procedures that might work or that I could order some carbon fiber insoles that would most likely help. So, when I saw these carbon fiber insoles from Unbound Sports, I ordered them! They slip under the original insoles of the shoe (which are then replaced). They are difficult to notice that they are in your shoe when you aren’t walking. When you are walking you notice that they don’t allow the toes to bend separately from the foot itself. For me this has made me tighten my shoelaces a bit more than I usually do because my heel has tended to rise up in the back of the shoe, but that’s a minor issue compared to the reduction in my pain in walking. It’s not completely gone (I think, but I’m not quite sure), but the intensity and frequency of it has certainly decreased. I’m very pleased! One thing I did notice is that the first day after wearing these inserts my lower calves were sore. They weren’t badly sore, but just a bit. I wondered why, not remembering any exercise I had done to irritate them, but then I remembered the insoles. These were probably forcing me to walk a bit differently – again, not a real problem as that pain was nothing compared to the pain in my (left) foot. After the second day I didn’t notice that anymore. I ordered the size 10.5, which is my shoe size, and these fit perfectly in my shoe. I’m using these in my hiking sneakers (my go to shoe) and they are working fine. I recommend these if you have a condition for which they would be useful. Read more

These get the job done. They are true to size and well-made. I got them for a navicular injury that needed a reprieve from flexing to heal. They do their job. I bought several pairs to equip an array of shoes at a bargain price. My injury is to my right ankle, but I use them in both shoes to make walking more even. I wear my Hoka trail running shoes for hiking, and the carbon plates mean that I don't risk stone bruises. The Hoka-carbon plate combination is much lighter than my Vibram-soled Keen hiking boots.

Very thick, which makes your foot rub against the top of the shoe, causing blisters and chafing. Didn’t feel any benefits. Read more

Exploring new ways to enhance comfort and performance and with a more active lifestyle, I recently tried out a pair of Carbon Fiber Insoles. I’ve had foot and ankle problems that have slowed me down in recent years. These insoles added a subtle yet appreciable spring to my step. It's not a dramatic difference, but it's enough to feel a boost during physical activities. My son also gave them a go on the basketball court and was even more impressed with the results. The insoles are thicker and stiffer compared to others we've used, which is a double-edged sword. While they offer more support and a noticeable improvement in action, they're slightly less comfortable for everyday activities. It's a trade-off, but one that could be worth it depending on your needs. If you're looking for an insole that adds a bit more power to your sporting endeavors, these Carbon Fiber Insoles are a solid bet. They might take some getting used to for regular wear, but the performance boost during sports activities is undeniable. Thanks for reading, and here's to more comfortable and energetic steps ahead!
