When holding them side by side, Vktry feels like a metal plate while the standard shoe insole feel like soft construction paper.

I cannot say I notice a huge difference using these insoles to others besides maybe the injury support. We are confident that our VKs can help athletes reduce lower leg and foot injuries including Turf Toe, Lis Franc, and Plantar Fasciitis. Carbon fiber in footwear is nothing new and is now being used heavily by brands like Nike, especially when it comes to performance running. The first day walking out on the golf course, I wore them for 13 holes and realized I should take them out since I had long passed the suggested 30 minutes on the first day. However, they are relatively expensive when compared with similar fibers, such as glass fibers or plastic fibers.

It's important to note that VKTRY Insoles are also proven to protect from injury, and no governing body would have it in their best interest to ban something that's proven to protect their players.

VKs come in 5 levels of flexibility because a bigger athlete generates more ground force than a smaller athlete.

We accommodate for these differences by having different foam cushions: yellow is 7mm thick, black is 4mm and red is 2mm. Normal insoles are primarily made of cellulose paperboard, a flimsy, sometimes spongy or cushioned foam-like material.

In another pair, my foot fit, but I could feel the edges of the insole near the toe space in the shoe. I did feel a slight increase in my vertical, but was very uncomfortable to the point where my feet went numb. VKTRY Insoles are designed to be highly personalized based not only on shoe size, but also based on body weight. I have used carbon fiber insoles in my cycling shoes too and there is tons more power in my stroke there too.I received the insoles 2 days ago and wore them in my spikeless golf shoes for 5 to 6 hours both teaching and playing on the course. This is our most common complaint and the easiest to remedy with a free exchange for a new pair that will be less rigid and more comfortable. She did end up rolling her ankle just today, so she will have to discontinue using them until the sprain heals and muscle memory of the movement. While a higher Pro Level may provide more spring, it’s very important that you are able to comfortably flex your feet for the insoles to be effective.
