Boots - make your feet, body and your boots last longer


If you are looking for insoles for your boots, you are probably also on your feet all day.

We’re often asked, “Which insole design should I get?” Here’s the inside scoop. All of our styles work exactly the same way, so the insoles that will work best for you depends entirely on the boots you have or are planning to get. Our insoles do not work anything like any other insoles. They restore proper posture to your feet and body which will enable your feet to cushion themselves better, balance your feet so you don't over pronate and supinate when walking on flat ground. ProKinetics® Insoles will not only make your feet feel better, but your entire body. Listen to the firemen below as they share their experience. One comment we hear all the time from our customers: "I have more energy at the end of the day".

There are all kinds of boots. Some of them look very good and are not for use in mud or the shop floor and others are special purpose boots. We have insoles for them too, and even for the boots you can't put insoles in. They are usually fashion boots and for them we have the Solemate® MicroLift™ that can be attached directly to the feet. We've got you covered.

Two years ago we asked our local Olympia, Washington Fire Department to give us their opinion on the ProKinetics® Insoles.

Being an U.S. Army Infantry Officer in the mountains of Afghanistan, I use my feet daily to accomplish my mission. Over the past 2 years I have suffered from plantar fasciitis and Metatarsalgia due to my Morton's Foot and the excessive weight I have carried in body armor, weapons, and gear both in the palm groves of Iraq and sheer mountains of Afghanistan. I have tried custom orthotics, physical therapy, and every plantar fasciitis night splint, stretch, and treatment option in the book. My feet being so important to my profession, I continued to search and eventually found my solution in Prokinetics insoles. They are both comfortable and durable in my combat boots and workout shoes and assist me as I bring the fight to the enemy in the Global War on Terrorism. CPT MIKE SNODGRASS US ARMY INFANTRY

Test Yourself

When testing yourself to determine how much you over pronate, you will also discover why you pronate.

This exercise simulates what happens when you walk, and is an approximation of how much you structurally over pronate.  This is most easily done in front of a long mirror or with the assistance of a friend. 

Step 1

First, stand on a hard surface with your feet comfortably apart, toes straight forward and feet parallel.  Lean slightly forward and bend your knees so that your hips drop 8-10 inches straight down. Don't squat, and keep your heels on the ground. 

Your knees should neither move inward (medially) nor outward (laterally) when you bend them, so if you have to, force your knees to move straight forward so they are alighed with the middle of your feet (third toes).

Next, from this position, move your knees slowly toward each other until you feel full weight bearing pressure under the balls of your feet behind your big toes. Not all the pressure, but at least as great as anywhere else under the foot.

Next, with knees in that position, draw an imaginary line from the middle of your knee straight down to the ground (the blue line in the picture)

6.0 mm:  If the line touches your feet in the orange range, you will do best with 6.0 mm Ultra Thin Insoles or add the orange wedge to your ProKinetics® Replacement Insoles. 

3.5 mm:  If the line touches your feet in the red zone you will most likely do well with 3.5 mm Ultra Thin Insoles or without adding the orange wedge to your ProKinetics® Replacement Insoles. 

Step 2

The wear pattern of your shoes indicate how you respond to your own structural pronation (what you just measured).

Over 60% of people who over pronate need to start in 3.5 mm insoles and graduate to 6.0 mm later. 
You are in this group if you tend to have an outside heel strike with a wear pattern that tracks forward on the outside heel and if you have a middle to outside wear pattern in the forefoot.

If in doubt, you can purchase the Perfect Fit™ which like the ProKinetics, contains all the components you need to start conservatively and graduate to more Kinetic Technology™ (forefoot wedge) if you need it. 

Rule of Thumb: If your shoes wear hardest from the middle toward the outside edge, you should always start in 3.5 mm or the red wedge. If you wear your shoes hardest from the middle toward the inside edge of your shoes, and if the knee bend test indicates you need 6.0 mm, you can start with 6.0 mm or the orange wedge. When in doubt, always be conservative. This is a technology where more is not better unless you actually need it.

The orange wedge attaches on top to provide 6.0 mm correction.

Stand with feet parallel and do a 1/4 knee bend.

Observe how far the knees have to move inward in order for the inside of the foot to become weight bearing.

If your wear pattern looks like any of these you will do best starting with 3.5 mm insoles and go to 6.0 mm after 7-10 days.

If your wear pattern looks more like this, you can start directly with 6.0 mm correction if needed.
