Football Carbon Fiber Insoles

Built For Explosive Starts & Confident Cuts

Q: Are VKTRY Insoles good for offensive and defensive linemen, or just skill players?

Both, but in different ways. Skill players can benefit most from the energy return component — faster first steps, higher verticals, quicker acceleration. Linemen can benefit most from the shock absorption and stability features: the carbon fiber base can help lessen the cumulative impact loading that builds up over a full game of physical contact, and the stability profile can help maintain foot positioning during blocking assignments and pass-rush moves. The flex level is calibrated to body weight, so heavier athletes get an appropriately stiffer base — linemen aren't using the same spring rating as a 165-pound cornerback.

Q: What if VKTRY Insoles don't fit after ordering?

"For a guy my size, I need every advantage I can get to show I can move. The VKTRYs just make you feel more explosive, like you're getting more out of every step. I'm not taking these out of my cleats anytime soon."

Kenyon Sadiq, TE

"The Combine is the one day where everything you've worked for comes down to a few seconds. I could feel the VKTRYs giving me that extra push off the line. There's a good reason so many of the guys out there were wearing them."

My son was experiencing some knee pain. After a physical therapist recommended insoles I began looking for the best I could for him. Let me say VKTRY insoles did not disappoint! After the break-in period, his knee pain was gone within a week. I asked him how they felt, and he replied, "Dad, it feels like I'm running on clouds." His speed increased, take-off speed improved, and elusiveness became more pronounced. I believe 100% VKTRY insoles were a contributing factor to leading his team to 3 local NFL FLAG Championships and prepared him for his next journey into tackle football.

I am a professional football player who recently suffered an ankle fracture. I have arthritis in both of my ankles and knees from wear and tear over my last 15 years of playing (since high school). I wanted to get the insoles anyways to help with my performance but once injured I realized, the time is now. I used it for recovery while healing and it helped tremendously. It takes the load off while walking and makes day to day life feel fantastic. Now that I’m back to play, it makes playing feel effortless. I recommend these to anyone, regardless if you’re an athlete or not, as I began my journey not as an athlete but a person with lower extremity pain. 10/10, this product is unmatched.

Reviews, something I don't do. But for this product, I have to! After reading the information on the insoles, I was impressed and encouraged by what I read. My son has been dealing with patella tendonitis this football season limiting his speed and agility. PT visits had recommended buying insoles which yielded no difference in performance and support. However, after having my son put these into his cleats at halftime of his game yesterday. I watched a massive difference in speed and agility at kickoff coming out of halftime. I immediately turned to his mother and said "Look how much faster he's moving!" Speaking to my son after the game, I asked him how much the insoles helped. He said, "Dad these things are awesome" and I was able to go full speed! Team VKTRY this product does exactly what I was hoping it would. thank you!!

My son plays college football and had offseason foot surgery. He was having difficulty with his recovery and returning to normal football activities. We were then introduced to Matt at VKTRY who assisted us in getting custom inserts for his trainers and his cleats. The inserts made a huge difference in helping him turn the corner. They even replaced (for free) one set of inserts after we lost one set. Great product and great customer service.

It only took one week for my son to break in the insoles for football. He doesn’t complain anymore about his feet being sore and no more blisters on his feet. I have tried many insoles by different company’s. Nothing beats the Gold VKs insoles they are worth the price.

Bought these for my son for added support in his football cleats. He was hesitant to wear them because initially he thought they’d be too tight on his feet. The gold insoles are a little thicker, so he wore a thin sock. After wearing them to practice, he said they felt good. His feet no longer ache and they are very supportive. I highly recommend for all athletes.

I ordered these to help with my knee (recently coming off an injury) so I thought it would help ease me back into playing (college football). I got an insole that did not fit my cleat at first so they switched it for me hassle free and without question. Now that I have my new size I absolutely love them. It takes a lot of stress off of my knee!! 11/10 would recommend

FAQ

How do VKTRY Insoles specifically help football players?

Football demands different things from different positions — explosive first steps for skill players, sustained power for linemen, and sprint speed for receivers and defensive backs. VKTRY's carbon fiber baseplate stores energy at foot strike and returns it on push-off, which can help maximize ground force production — the power behind a faster first step, a more explosive jump, and quicker acceleration. That's why VKs are used by players at every position from youth through the NFL. Individual results will vary.

Will VKTRY Insoles actually improve my 40-yard dash time?

They can help. VKTRY Insoles are designed to optimize energy return, which can help with acceleration and sprinting. In independent testing, athletes tested saw, on average, a 0.12-second improvement in their 40-yard dash time while wearing VKTRY Insoles versus standard insoles. In a sport where 40 times are measured to the hundredth of a second, that kind of margin can matter. The mechanism: the carbon fiber baseplate stores energy from each stride and returns it on push-off, which can help reduce energy loss with each ground contact and improve stride efficiency. Individual results will vary.

Are VKTRY Insoles legal in the NFL, NCAA football, and high school play?

Yes. VKTRY Insoles are not restricted by the NFL, NCAA, NFHS, or any football governing body. They are classified as standard orthotic insoles, which are permitted equipment at all levels of play. There are no carbon fiber insole restrictions in any football ruleset. VKs are worn by both amateur and professional football players, including NFL players. No league has issued any prohibition on their use.

Do VKTRY Insoles fit in football cleats?

Yes — and fit in football cleats is one of the most common questions because cleat volume varies considerably between skill-position cleats (low-cut and tight) and lineman cleats (higher cut, more volume). VKTRY accounts for this: the insole is slim by design and replaces the factory insole rather than sitting on top of it. Skill-position players using lightweight cleats should remove the factory insole before inserting VKs. If fit feels tight, the VKTRY team is available to advise on sizing — all orders include a 90-day money-back guarantee.

Are VKTRY Insoles good for offensive and defensive linemen, or just skill players?

Both, but in different ways. Skill players can benefit most from the energy return component — faster first steps, higher verticals, quicker acceleration. Linemen can benefit most from the shock absorption and stability features: the carbon fiber base can help lessen the cumulative impact loading that builds up over a full game of physical contact, and the stability profile can help maintain foot positioning during blocking assignments and pass-rush moves. The flex level is calibrated to body weight, so heavier athletes get an appropriately stiffer base — linemen aren't using the same spring rating as a 165-pound cornerback.

How do VKTRY Insoles help protect against common football injuries?

Football's most common lower-body injuries — turf toe, plantar fasciitis, ankle sprains, knee ligament stress, and shin splints — involve some combination of excessive impact loading and foot instability. VKTRY's carbon fiber base provides structural stabilization that can help reduce the torsional forces at the ankle and knee during contact and cutting movements, and the shock absorption can help reduce peak ground reaction force on the lower body. In a field study of 263 Division I football players across four universities, the teams reported 41% fewer foot and toe injuries and 22% fewer lower-leg injuries during the season players wore VKTRY Insoles, compared to the prior three seasons. Individual results will vary. VKs are not a medical device. Consult a physician or athletic trainer for any injury concern.

What if VKTRY Insoles don't fit after ordering?

Every order comes with a 90-day money back guarantee.
