VKTRY Performance Insoles from VKTRY Gear are engineered specifically for sports usage. The insoles are designed to return the energy an athlete generates into explosive power, which translates to improved speed and agility. The insoles feature a patented carbon fiber design that, according to third-party research, has been proven to increase explosiveness by 9.3%. This increased explosiveness translates to 0.12 seconds faster speed in a 40-yard dash, 1.6″ higher marks in vertical jump, and 4″ farther distance in the broad jump. In addition to increased explosiveness, VKTRY Performance Insoles provide increased support, stability, and shock absorption. This, in turn, helps prevent injuries from plantar fasciitis, turf toe, stress fractures, and shin splints. Over 150 pro and NCAA teams wear VKTRY Performance Insoles. The company offers a 30-day risk-free trial.
