Built For Ground Force & Explosive Energy

Baseball and softball demand short, explosive bursts — first-step quickness off the base, hip rotation through a swing, and rapid deceleration when fielding grounders. VKTRY's carbon fiber baseplate stores and returns energy with each ground contact, which can help with faster acceleration down the line and more rotational force through the lower body during a swing. Unlike foam insoles that absorb and waste that energy, VKs are designed to give it back. Each pair is also calibrated by sport and body weight, so the flex profile is tuned for the demands of baseball specifically — not a one-size-fits-all design. For extended games and doubleheaders, the shock absorption component can help reduce the cumulative leg fatigue that builds over a long season.

Yes — and this is one of the most underappreciated benefits. Every powerful swing and pitch delivery starts from the ground up. The kinetic chain from the feet through the legs and hips is where bat speed and arm velocity originate. VKTRY's carbon fiber base can help improve ground force production, meaning more energy is transferred up the chain with each swing or delivery. Independent testing has shown that athletes tested generated an average of 9.3% more explosive force when wearing VKs, which can translate into greater rotational power for hitters and more drive through the mound for pitchers. Results will vary by individual.

Shin splints are one of the most common complaints among softball pitchers, who spend entire games in a repetitive drive-and-push stance that loads the lower leg repeatedly. VKTRY Insoles can help reduce peak ground reaction force at impact, helping to absorb shock that would otherwise travel up through the shin. The carbon fiber baseplate can also help stabilize foot position through each stride and pitching motion, reducing the micro-movements that contribute to shin splint development over a long season. If you're currently managing shin splints, consult your physician — but many softball athletes report significant improvement in comfort once they've completed the break-in period with VKs.

Yes. VKTRY Insoles are legal for NCAA baseball and softball. They are not prohibited by the NCAA, NAIA, or any professional baseball league (MLB, MiLB). They function as a standard orthotic/insole insert, which is permitted equipment under all major governing body rules. No governing body has issued any restriction on carbon fiber insoles in baseball or softball. VKTRY Insoles are worn by both amateur and professional baseball players, including at the MLB level.

Yes. We customize VKTRY Insoles based on several factors, including whether they are intended to be used inside baseball and softball cleats, replacing the factory insole. Because cleats typically have less cushion volume than training shoes, the slim carbon fiber profile of VKs fits cleanly without creating pressure points or raising the foot uncomfortably in the heel cup. VKTRY calibrates the flex level to sport and body weight, so the insole is tuned to the specific demands of cleat-based movement. It's recommended to remove the factory insole before inserting VKs for optimal fit.

Standard orthotics and foam insoles are designed primarily for support and comfort — they absorb impact and provide arch support, but they don't return energy. They're passive. VKTRY's carbon fiber baseplate is an active energy system: it stores the energy of foot strike and releases it as the athlete pushes off, functioning similarly to a diving board. For a sport where speed off the base and power through the swing are measurable competitive advantages, that energy return is meaningful in a way that foam never can be. VKs also carry APMA acceptance for their positive contribution to foot health, so you're not trading injury protection for performance.

Yes. VKTRY is trusted by athletes at all levels, including professional baseball. Gunnar Henderson, one of the most dynamic players in Major League Baseball, is a VKTRY athlete. VKTRY is also an official partner of Perfect Game, the nation's largest youth baseball scouting organization, meaning players from youth travel ball through the pros are using VKs. VKTRY Athlete partners, like Gunnar Henderson, are compensated for their partnership.
