Improved Ground Force for Explosive Power

The gym is where VKs can offer real value for non-sport-specific athletes: the energy return is designed to help support performance on explosive lifts (squat, deadlift, box jumps, lunges), while the stable carbon fiber base is built to help support proper foot positioning under load. Many athletes report feeling more drive through their legs on compound movements — the same energy return mechanism associated with vertical jump improvement may also help the drive phase of a squat or the push phase of a deadlift. The shock absorption may also help reduce foot and joint fatigue for athletes doing long cardio sessions or HIIT circuits. Individual results will vary.

VKTRY Insoles are ideal for CrossFit, HYROX, DEKA, and other high-intensity hybrid workouts, providing stability, energy return, and support through every run, lift, and transition. They’re also perfect for everyday workouts, offering comfort and support for everything from gym sessions to training days.

Yes, independent third-party studies have shown that athletes tested, on average, increased their explosiveness by 9.3%. For fitness enthusiasts, this improvement can translate into more powerful sprints, jumps, and strength training, enabling you to push harder and achieve more explosive movements.

Yes, VKTRY Insoles are designed to stabilize the foot and lower leg, reducing twisting or torquing forces that lead to injury. The carbon fiber baseplate provides enhanced support, shock absorption, and energy return, which can help athletes, such as those participating in fitness training, protect against foot, knee, and other common lower leg injuries during high-intensity workouts.

Yes — training shoes (Nike Metcon, Reebok Nano, NOBULL, New Balance Minimus, etc.) typically have the most interior volume of any athletic footwear, making them the easiest fit for VKs. Remove the factory insole and size per the VKTRY chart.

Yes, they can be. The structural arch support in VKs is designed to help both flat-footed athletes (who tend to overpronate and may benefit from the rigid base stabilization) and high-arch athletes (who may benefit from cushioning and reduced impact transmission). VKTRY is APMA-accepted, recognizing the insole's positive contribution to foot health across a range of foot types. VKs are not a medical device — consult a physician for any diagnosed foot condition.

VKTRY Insoles are made with a full-length carbon fiber base plate, in which the flexibility (we call "Pro Level) comes personalized to your sport & weight. When you bend your foot to walk, run or jump, your foot is putting energy into the ground. A standard foam or plastic insole would disperse (and waste) that energy. VKTRY Insoles absorb that energy and then return back to you, similar to how a diving board or trampoline would. Athletes are proven to see greater explosiveness & ground force when wearing VKTRY, resulting in higher verticals and faster sprints.
