Supination Control


Most people who supinate wear the outside corner off their heels in a hurry, and often wear the whole shoe out along the outside edge first.

If you're here to figure out what to do about it, you're in the right place. If you're looking for gel or any other type of soft cushioning, we can hopefully demonstate to you that we offer something far better that will normalize and soften your gait.

This is NEW TECHNOLOGY. This is the health smart way so please, don't start "jacking up" your arches like a car with a flat tire.  It imobilizes your arch as much as it immobilizes your car. For most people arch supports are not a desirable solution.

Pronation is a natural motion, and like most things natural, too much and too little is the problem. The right amount of pronation serves to cushion your feet, to soften your heel strike and to balance your body. Too much pronation causes excessive torques in your knees and hips, it tilts your hips forward and tears down your posture. Too little pronation makes your heels hit the ground like a jack hammer sending shocks up your spine and waking downstairs hotel neighbors with every step. Thump, Thump! Who hasn't experienced that.

Very few people who supinate have a structural reason for doing so. In fact most supinators structurally over pronate, but subconsciously they compensate for it and end up overcompensating, throwing their feet into supination instead. So, the trick to fixing supination is to take care of the over pronation so the brain stops trying to fix it!

You have Muscles to Control Pronation   •   •   •   •   •   • 

It is easy to proove too. Just pick up a towel from the floor with your feet and you'll see. It makes your arch rise, and it sends your big toe to the ground. Logic tells you that if you plop your arches on top of an arch support, those muscles will go lazy, and that brings on a whole new set of problems most people want to avoid.

Arch supports weaken your feet

Most People do not need arch supports

NO - If you have functional arches, even if they are low, you don't need arch supports.

NO - If you have high flexible arches, you don't need arch supports. 

Arch supports are helpful under certain conditions

YES - People who have flat feet benefit from arch supports.

YES - People who suffer from Plantar Fasciitis (heel pain) benefit from using arch supports temporarily while the fascia attachment heals. 

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.

Getting to the root cause

If all your metatarsals and toes are on the ground, figure A, you'd be balanced and your arch would be stable--not dropping.  The problem is that for most people, the big toe (and first metatarsal) h Morton's Foot Syndrome (shortened first metatarsal and deeper first web space).  It is an issue of the bones in the foot - specifically the head of the Talus (ankle bone).  Because of an upward rotation of the head of the Talus, the first metatarsal and the big toe literally have to travel a small distance toward the ground to become weight bearing, and in the process the inside of the foot, the arch, collapses. 

The elevated first metatarsal also causes the ankle to roll in and an internal rotation of the leg.  You were born with the elevated first metatarsal which greatly impacts your gait and posture. 

The muscles controlling your arches were stronger when you were younger and more active. By the same token, children today are less active and weaker, and as a result, they suffer with back aches and other musculoskeletal pain in record numbers.  Most people try to control their arches using the wrong muscles - we call them “bracers”  because they brace their muscles against hyperpronation.  That leads to tired calf muscles and shin splints.  We know with certainty that faulty foot mechanics and poor posture catches up with you as you age.  By the age of 40, most people suffer from some kind of foot and posture related musculoskeletal pain.
