I‘m a believer in good shoes and supports. Why? I competitively raced for a decade (10k, half and full marathons) and without the full functional of your feet (impacting your legs, knees, hips, alignment, then upper body), you’re in for progressive issues. I had nutritional, medical, and athletic professionals. But all it took for me to skip a major race was an injury. Which is how I learned to be proactive. These insoles are both performative and proactive.

They are the perfect addition to 1. help offset foot structure impediments (flat foot, arch issues), 2. provide incredible lightweight stability and ’spring‘ response (carbon fiber insert) which can increase performance, and 3. yes, it‘s necessary to say - make your feet feel fantastic! I could not believe how amazing these felt on my feet.

My son’s job requires him to be on his feet 10.5 hours/day and he has flat feet. I figured he needed these more than me and he replaced his shoe brand insoles with these and said they are 5 stars!

Do I recommend these insoles? Absolutely!

The arch support layer absolutely does make a difference in these fiber insoles, especially during longer sessions where my feet usually start protesting. The whole 2-in-1 boost system definitely helps with absorbing impact; landing feels far more comfortable, taking some pressure off my knees which is exactly what I wanted. They offer really good stability during quick lateral movements too. The only thing I'd mention is that because of the carbon fiber material, they are quite stiff at first, so you shouldn't expect immediate plushness. Give them a couple of workouts to fully settle in, and you'll appreciate the firm, responsive feeling they provide under pressure.

These insole are certainly the best I've ever tried. They're stiff, yet do have a little bit of give to them, so it's not like your standing or walking on concrete, but rather that your foot is supported toe to heel.
The arch fit perfectly and after wearing all day, I experienced no pain, weakness or tired feet. That's been unheard of for years! I've tried different expensive shoes, insoles and other supports, and always knew within the first day of wearing whether they were going to be a success or not. All but these have been a definite ‘not’.
These are thin, yet extremely sturdy, and very durable. They function as supportive additions to your shoes. Taking care of your feet is so important, especially as you get older, and these insoles are an imperative tool in having pain free feet, and steady walking. These are an excellent value.

This is quite the marketing experience... I broke a sweat just reading all the material. So, let me break it down. This is a two part system that works together to enhance your steps and eliminate and twisting of the shoe. The first part is the carbon fiber inner insole, if that is even a thing? You want this part to fit your shoe without any trimming. If it doesn't fit, just stop there and order another size smaller or larger depending on your situation. This is the part that is to prevent and torsionally twisting of the sole. It will suppress bending, but this is where you get a little springing action from in your steps. The carbon fiber inners are interchangeable they can be left or right, and they are very firm.

Once that is settled in your shoe, you add the insole to the mix. Now let me explain here, you want these to go in shoes that have laces and a little room to grow because these will add a small bit of height. The soft insole can be trimmed to fit if it is too large. The insole adds wonderful arch support and springy softness in the ball of the foot. I haven't done too much jumping with these, I added them to my trail running shoes (that I don't run in). I use them for walking up the hills near my home instead. They are wonderful for that. The carbon fiber makes a difference, as I don't have to worry about my shoes twisting on a rock etc. I have another pair of insoles that utilize the "Poron Vive" in the heels, whereas these insoles use it near the ball of the foot. This pair utilizes the other kind of "Poron Comfort" product in the heel, the " Poron comfort" and let me tell you it is so comfortable in the heel. It absorbs any shock you can throw at it. My feet are rather tender due to fibromyalgia, so these products make a difference for me. The other area of the insole is the big toe area that has a grippy silicone product there to help your toe really grip onto the carbon fiber for the "lift off". You really feel your step being more productive as the carbon fiber is preventing any bending so you can really dig in.

When put together it's a formidable system that works for people that need attention to their gait, or the liftoff for a jump. They really help me keep my gait more correct and prevents any twisting while scrambling up hillsides. It has great attention to keeping the arch lifted, while at the same time being comfortable while doing it. They feel as if they will be very durable and hold up to anything you can throw at them. I mean, can you even break carbon fiber? If the insoles ever wear out, you just have to replace them, the carbon fiber should last as long as you do !! When you consider that, the price makes more sense and you feel a true value for your money. You can even save more now if you buy the system with the extra insole. True, I'm not a professional athlete, but I can really appreciate what these insoles can do for you in your sporting environment. The product looks exactly as it is pictured so I won't bore you with amateur photography !!

These are amazing. They add a significant bounce to my step with a real feeling of lift-off. The arch support is solid and the shock absorbancy is serious. They helped me to reduce foot fatigue, added support, and protected against hard impact jumping/running. They fit perfectly inside my shoe. I have high arches and these really give me the support I need.
