This post is a review, and ringing endorsement, of Kingfoam insoles.
Kingfoam insoles are among the best products I have ever encountered. I endorse them to/for anyone, not just skaters. There is literally no product in modern day production that I speak of as highly as I do of Kingfoams. If you are an older skater with any foot/knee problems, you should absolutely give them a serious look.
First, what makes Kingfoams so good? They are made of some crazy-ass foam that absorbs absurd amounts of force / impact, yet still provide for great board feel. I no longer fear Primo on kickflips. Let me restate that, I no longer fear Primo on kickflips. Yes, you read the correctly. They are that good. Bruised heels? Never again.
Despite what you may think of Aaron Kyro / Braille Skateboards, he does a damn good video review of Kingfoam insoles. Watch this clip and you’ll see an astonishing visual display of the impact absorption I mentioned. The video is also pretty amusing, too. Here is a link to Aaron's video.
Kingfoam makes several different types of insoles. People have different types of foot arches. Some shoes accept insoles, others do not. Hence, navigating all of it can be a little confusing. Hopefully this post will help.
Let’s start with the basics. First, for Kingfoams to really function, you need a shoe that comes stock with a removable insole (e.g. Vans Pros, Adidas, etc.). A shoe like the NON-Pro Vans is going to have some problems because there is no removable insole. Adding one will probably make your shoe fit too snuggly/tightly. That’s bad.
Second, you need to know what type of arch your foot has (low, medium, or high).
This video shows a very simple and easy way to figure that out. The video suggests cardboard. IMHO, newspaper works just as well, if not better.
Third, take a look at the Kingfoam Buyer’s Guide, and note which of their insoles correspond to what type of arch you have.
Last, and this is where things get a little cloudier: pick out which insole you want. Here is what I can tell you about them from personal experience.
I have a mid arch foot, and skate in Vans Pros. I hate the stock “ultra cush” insoles that comes with Vans. To me, they often feel like heel has sogged after a very short period of time. My knees and feet would often get sore after skating for a while in Vans. Many people have said this, and switched over to Nike as a result. I also work a job where I am on my feet all day. At the end of a shift, my feet are just spent/sore. Once I replaced the stock Ultra Cush insoles with Kingfoams, I never had these problems again.
I have tried two different types of Kingfoams. The standard “5mm Kingfoam Insole” ($19.99), and Kingfoam "Elites" ($29.99). I wear the 5mm ones in my work shoes, and use the Elites in my skate shoes. The Elites offer a bit more impact protection. Hell, Jaws even wears them (and for good reason). Both the 5mm version, and the Elite version, fit great in Vans shoes. The 5mm ones comes in specific sizes, and the Elites are cut-to-fit.* Both of these do not work in Adidas. The stock Adidas insoles have a tad bit of arch support on the side. The two types of Kingfoams I use do not have any arch support, so when you put them in a pair of Adidas, they feel really weird. I imagine one of the Kingfoams with arch support would work in Adidas, but I can't speak with first-hand knowledge. I have no idea how they fit in other skate shoes, but I am sure you could find out without too much trouble. Google. Slap forums. Etc.
I have never tried the Gamechangers, because I am so enamored with the Elites. Someday I’ll get a pair and post a review. I have heard nothing but great things about them. Kingfoam also makes some very thin insoles. These might work in shoes that do NOT have a removable insole, but I would be skeptical of it. There is no way they could function as well as the Elites.
*Always cut these a bit too big at first, and then slowly trim to exact size. If you cut them too small, they will float around under your foot, and be extremely annoying, if not useless. To cut them, just remove the stock insole, and trace them against the Kingfoam, and then cut down with scissors.
