VKTRY PERFORMANCE INSOLES - TRAINERS
Description
How VKs Work
VKTRY Carbon Fiber Insoles Increase Ground Force.
Simply by putting VK's into your shoe or cleat, you can rapidly generate more force into the ground.
The combination of increased ground force (+8.1% peak force) and increased explosiveness (+9.3% rate of force development) immediately translates to running faster and jumping higher.
Most sport insoles are made from foam and plastic and provide virtually no energy return. 
How VKs Increase Ground Force:
- Patented, Curved Shape
- Full-length Carbon-Fiber Base
- Customized Flexibility
Unlike traditional insoles that offer one product for all body weights, VKTRY Performance Insoles are available in 5 flexibility levels (“Pro” levels).
Using athlete weight, foot size and sport, our proprietary algorithm determines optimal “Pro” level based on how much deflection force an athlete can comfortably exert on the VK. This force is stored and released back to the athlete.
