These are proper solid insoles—definitely built for performance rather than comfort alone. The carbon fibre gives a firm, supportive base that doesn’t squish under pressure, and you can feel a bit of extra spring with each step. Great for running or gym work where you want more structure and less impact on your joints. They’re not the soft, cushiony type, though, so probably not ideal for narrow shoes or all-day casual wear. That said, if you’ve got the space and need proper arch support with a bit of energy return, these are well worth a look. Just the right mix of support and stability.

Given the thickness of these insoles you might find that it makes your shoes very cramped and you might need to massively loosen your laces to make them remotely usable. I was unable to use these with my Nike running trainers but my adidas trainers were totally fine.That said, if you have the space in your shoes these are incredibly comfortable and offer brilliant support. As expected, I did find running in these to be noticeably easier and that was reflected in my 5km times which were around 40-50 seconds faster on average. You almost have a spring in your step, especially on uneven terrain.It's worth noting that carbon fibre insoles will likely void any of your times in more serious runs but if you're just looking to beat your friends or make runs a bit easier then these are fantastic budget friendly option instead of buying running trainers with built in carbon fibre soles.

I tried these carbon fiber sport insoles out while coaching volleyball and found that they were comfortable. The heel is well cushioned and there is a lot of arch support. So much arch support that people with flatter arches might find the insoles uncomfortable. I've tried other carbon fiber insoles and could feel the carbon fiber. With these ones I couldn't feel the carbon fiber which made them even more comfortable for me. I didn't have the occasion to play any type of sports with them in my shoes so I personally don't know how responsive they are when playing.When my son learned there was carbon fiber in the insoles he immediately wanted to put them in his shoes. He plays volleyball for his high school team and does a lot of jumping. He said they are still comfortable after a couple months of using them. He feels like they help him jump higher and run faster.These insoles were roughly half the price of other carbon fiber insoles. They feel durable and have held up under my son's constant use. I would recommend at least giving these a try to see how they work for you.
