Made With Premium-Grade Carbon Fiber

Many carbon fiber products use low grades of carbon fiber. Not us. The woven pattern you see on our carbon fiber plates is not printed. Those are woven layers of a purer grade of carbon fiber, known as aerospace grade. It's more flexible, stronger, and more durable than the cheap composite plates used by other manufacturers.

Why We Customize By Weight

VKTRY Insoles customize the stiffness of their carbon fiber based on your weight. Why? Different athletes exert different levels of force through the ground. Based on your body weight, we can optimize the reflex action of the carbon fiber plates. Unlike the standard plates in super shoes, you’ll get a plate acutely tuned to the forces you are creating.

Why Trail Runners Love VKTRY

POWER UPHILL

The carbon fiber plate is great for generating maximum power when climbing.

ENERGY RETURN

Get great energy return on every stride.

BOOSTED DOWNHILL SUPPORT

The carbon fiber plate is extra noticeable on steep downhill descents, offering extra knee support.

“I had gotten a pretty nasty case of IT Band Syndrome and never had my feet looked at. Turns out I supinate and nobody really makes running shoes for us (wide feet too) so I needed insoles. Got a pair of custom VK's and haven't looked back. Im not the greatest runner but I'll log about 35-50 miles a week depending on my other cross training and they have been great. I don't have much knee pain and just did a 9 hour trail race with zero issues. No foot pain, no back pain. Honestly I felt great. Since getting the VK's I have seen my power output average increase by nearly 100 Watts (yes I collect the data on every run, tested them on the same route, same shoes, similar weather, same pace) and I definitely feel more efficient when running. I would recommend these to anyone especially us novice runners in our 40s trying to stay injury free”
