The VKTRY Performance Insole

The VKTRY Performance Insole is the first-ever sports insole designed to return the energy an athlete generates as explosive power, speed and agility. The VK’s patented carbon fiber design is scientifically proven to increase explosiveness by an average of +9.3%. Sports Medicine experts agree that VKs also provide added support, stability and shock absorption to help protect against injuries such as plantar fasciitis, turf toe, stress fractures, shin splints, etc. See why athletes at over 150 Pro and NCAA teams wear VKTRY Insoles and try risk-free for 30 days.

Our Performance Testing

VKs were independently tested at 3 different controlled testing facilities with over 77 athletes during the course of a year. Testing alternated with/without VKs, performing sprint and jump tests in random orders to reduce fatigue and placebo effects. All tests were conducted using laser timing mechanisms and digital forceplates for optimal accuracy and precision.

41% Less Foot & Toe Injuries.

263 Athletes across 4 NCAA Football Programs, Compared to Prior 3 Seasons


“The best way to treat an injury is to protect yourself from one.” 

“The VK is the best combination of injury protection & performance I have ever seen in insoles.”


“VKs represent a quantum leap in the world of performance insoles providing many of the benefits of custom made orthotics in an over the counter device."

"For the first time, athletes can experience stabilization, shock absorption, and propulsion in a device that is specifically tailored to their size and weight.  This is a game changer.”
