Whaddaya Think of these Shoes?

Would you put YOUR patient/client/own feet in them?

Dr Ivo Waerlop, one of The Gait Guys, discusses a common manufacturers defect to look out for, especially in people with rear foot problems. You have to watch out for manufacturers defects in shoes : )

Motion control Shoes + Internal Tibial Torsion = Knee Pain

Thinking about putting a motion control shoe under that foot to control pronation? You had better make sure you make friends with the knee, as it will often (depending on the compensation) be placed OUTSIDE the SAGGITAL PLANE. Like Dr Allen has said many times before , the knee is basically a hinge joint placed between 2 ball and socket joints, and it is usually the one to start grumbling...

"You do not have a shoe problem, you have a "thing in the shoe problem", meaning, it is you."

We say this so often in our offices.
"You do not have a shoe problem, you have a "thing in the shoe problem", meaning, it is you."
Translation: compromised mechanics leading to tissue overloading.
But we all have to strongly consider that injury is a result of the loading you have not trained gradually into, failure to adapt and accommodate, excessive mileage without adequate tissue recovery,

From the article:
"So Napier and co-author Richard Willy from the University of Montana reviewed the highest-quality research featuring randomized controlled trials and systematic reviews.
"What we see is that there's really no high-level evidence that any running shoe design can prevent injuries," Napier said."

Now, to be honest, in our (the gait guys) opinion, there are times we do recommend a change in the foot wear for a client, and it is often because it appears to be working against someone mechanics and is a contributory factor in their injury or complaint. And sometimes that shoe recommendation is a temporary one, and sometimes a permanent one. We can use a shoe to help us get to a better/faster end point. After all, when we sprain an ankle sometime a brace or crutches are helpful and protective, of temporary value. A wisely chosen shoe can act the same if we are dealing with an acute achilles tendinopathy or a painful bunion for example. And in those cases we might recommend a shoe that can give us an assist. Sometime, when appropriate perhaps it is a shoe with a stronger medial post, perhaps one with a higher or lower heel drop/delta, or more or less stack height, or perhaps a mid/forefoot rocker built into the shoe. The truth is, people come in with functional or "fixed" pathology and sometimes pairing up a shoe to help us around some conflicting biomechanics can be temporarily, and sometimes permanently, helpful. But, the shoe is never the only answer, a wise clinician has many things they can utilize, all the way up the kinetic chain sometimes.
The more you know, the better you can assist someone.

More Flip Flop Madness. Can a flip flop reduce impact forces?

Flip Flop Madness. Can a flip flop reduce loading/impact force? Maybe...

We agree that the increased ankle dorsiflexion moment is to try and keep the flip flop on.  This particular flip flop, the Fit Flop, has different gait parameters (see figure 2 in the article) compared to normal flip flops and barefoot. We hypothesize this is most likely due to the semi rockered design along with the heel cup. Rockered shoes reduce the amount of hallux dorsiflexion needed for forefoot rocker and reduce plantar pressures in the forefoot (1) What surprised us most were the decreased impact forces.

"The current study identified increased ankle dorsiflexor activity in flip-flop style footwear compared to barefoot, coupled with increased dorsiflexion in swing, assumed to be a mechanism to hold the shoe on the foot. The FitFlop limited foot motion in the frontal plane and significantly reduced loading at impact, compared to flip-flop and barefoot. However, it is not clear whether the reductions in these parameters are enough to reduce any potential injury or overuse injuries associated with flip-flop footwear and further, longitudinal, research would be needed to clarify this relationship."

Footwear IS Medicine

We always have said that "Shoes ARE medicine" Here's an article that supports that.

"Footwear plays an integral role in force distribution on the lower extremities, and choosing appropriate footwear is one of many strategies people can use to manage knee pain caused by joint disorders. When footwear is properly fit, force and stress can be shifted away from weaker parts of the knee, and the leg stabilized. This may lead to a significantly better quality of life for patients with knee problems, such as osteoarthritis (OA) and patellofemoral pain syndrome."

increased cushioning = increased impact forces (GRF)

increased impact forces = increased injuries?

possibly not...

 

footwear can impact injury and biomechanics but may not be the primary factor

a nice recap of the state of what we currently know about shoes, design and cushioning.

http://lermagazine.com/cover_story/running-shoes-and-injury-risk-rethinking-the-importance-of-cushioning-and-pronation

What do we have here and what type of shoe would be appropriate?

You are looking at a person with a fore foot varus. This means that the fore foot (ie, plane of the metatarsal heads) is inverted with respect to the rear foot (ie, the calcaneus withe the subtalar joint in neutral). Functionally translated, this means that they will have difficulties stabilizing the medial tripod (1st MET head) to the ground making the forefoot and arch unstable and likely rendering the rate and degree of pronation increased.

The incidence of this condition is 8% of 116 female subjects (McPoil et al, 1988) and 86% of 120 male and female subjects (Garbalosa et al, 1994), so it seems to happen happen more in males. We think this second number is inflated and those folks actually had a forefoot supinatus, which is much more common.

Fore foot varus occurs in 3 flavors:

  • compensated
  • uncompensated
  • partially compensated

What is meant by compensated, is that the individual is able to get the head of the 1st ray to the ground completely (compensated), partially, or, when not at all, uncompensated.What this means from a gait perspective ( for partially and uncompensated conditions) is that the person will pronate through the fore foot to get the head of the 1st ray down and make the medial tripod of the foot (ie, they pronate through the subtalar joint to allow the 1st metatarsal to contact the ground). This causes the time from mid-stance to terminal stance to lengthen and will inhibit resupination of the foot. 

Today we are looking at a rigid, uncompensated forefoot varus, most likely from insufficient talar head derotation during fetal development and subsequent post natal development. They will not get to an effective foot tripod. They will collapse the whole foot medially. These people look like severely flat-footed hyperpronators.


So, what do you do and what type of shoe is appropriate? Here’s what we did:

  • try and get the 1st ray to descend as much as possible with exercises for the extensor hallucis brevis and short flexors of the toes (see our videos on youtube)
  • create more motion in the foot with manipulation, massage mobilization to optimize what is available
  • strengthen the intrinsic muscles of the feet (particularly the interossei)
  • increase strength of the gluteus maximus and posterior fibers of the gluteus medius to slow internal rotation of the leg during initial contact to midstance
  • put them in a flexible shoe for the 1st part of the day, to exercise the feet and a more supportive; medially posted (ideally fore foot posted) shoe for the latter part of the day as the foot fatigues
  • monitor his progress at 3-6 month intervals
  • a rigid orthotic will likely not help this client and they will find it terribly uncomfortable because this is a RIGID deformity for the most part (the foot will not accommodate well to a corrective orthotic. Besides, the correction really has to be made at the forefoot anyways.

New shoe, old shoe. The rotation, it matters.

At this very moment i am responding to an email of a very sweet and extremely talented runner in Tasmania, I saw her months ago here in the USA as she travelled through. I find myself sharing a conversation with her at this very moment, one she likely knows, but one we all forget, or get lazy with. It is all about
"reducing one more risk factor, reducing one more sudden biomechanical change that can provoke changes in our loading response". 
This is nothing new for veteran Gait Guys brethren here, but we get 100's of newbies here each week, so it is good to remind all.
* Never underestimate the subtle changes in biomechanics that might come from a shoe change in a high mileage athlete. Sweat the small stuff, sometimes." Foam changes, foam loses its resilience with repeated compression cycles, foam deforms into your particular biomechanical loading habits. And sometimes your habitual loading cycles are subtle, but as the foam gives into them, the small thing mushrooms into a significant thing. IT can become a "tipping point" for your clients biomechanics. Something that was initially nothing, becomes something of significance. Help reduce your client's risk factors so you can stay focused on the things that matter, reduce those inner-mind rumbling thoughts of "i wonder if that is a factor". Take those off the table for all your clients, when possible.

We always want to get one more run in on a pair of shoes that is weak and limping its way into the finish line, on its final death throws. 
"Today's story: Bam, i got one more run in on these babies. 
Tomorrow's story: hey i wonder why i am having a little medial foot-arch-ankle pain today???" #facepalm
(not that this has anything to do with the client below, just slamming home my point)

"Dear _____:
Do you think switching to a newer pair of Zante's had any factor in this ? Did the shoe seems to guide the foot differently than the older pair ? Anything feel different ? Sometimes a fresh shoe today changes mechanics too much compared to the one you were just in yesterday (try in the future to have 2-3 pairs in rotation, switch up every run to a different one. Have one newer one in the rotation, another with 200 miles and one that is almost done. That way you are never burning down one shoe and then jumping in a new one. Always be finishing up on an older shoe and starting in on a new one, with one in the pocket in the middle wear milage.)
Now, onto your injury in question . . . .

Shoe drop has opposite influence on running pattern when running overground or on a treadmill.   Nicolas Chambon et al
https://link.springer.com/article/10.1007%2Fs00421-014-3072-x

To drop or not to drop...That is the question...

Like to run in Zero Drop shoes? Good... we do too... but look at this:

"Barefoot running induced higher loading rates during overground running than the highest drop condition, while it was the opposite during treadmill running. Ankle plantar flexion and knee flexion angles at touchdown were higher during treadmill than overground running for all conditions, except for barefoot which did not show any difference between the tasks."

So, if you want to reduce vertical loading rates, run barefoot on a treadmill.

Does this mean if we want to decrease vertical loading rates when running overground (NOT on a treadmill) we should run in shoes with a large drop?

It seems, according to this study, that kinematics are the same with barefoot but not with shoes.

Which is best for you? You decide...

“Too much tripping, soles worn thin. Too much Trippin and my soul’s worn thin.”

Scott Weiland


Take a look at these shoes which are basically a leather glove for the foot. Look at the wear pattern and how the lines of force travel from the heel, of the lateral aspect of the foot, across the metatarsal heads and out the great toe. To have you wear on the right is due to a left-sided leg length discrepancy.  She has a higher lateral longitudinal arch as evidenced from the absence of where just anterior to the heel.  Looks like she’s getting her first Ray to the ground, Eh?

The Pitfalls of Motion Control Features.

Welcome to Monday, folks. Today Dr Ivo discusses why not all shoes are created equal and why you need to understand and educate your peeps about shoes!

Internal tibial torsion is when the foot is rotated internally with respect to the tibia. When the foot is straight (like when you are walking, because the brain will not let you walk too internally rotated because you will trip and fall), the knee will rotated OUTSIDE the saggital plane (knee points out). Putting a medially posted shoe on that foot rotates the foot EVEN FURTHER laterally. Since the knee is a hinge joint, this can spell disaster for the meniscus.

More on the Minimalist Debate  “Nearly a third (29%) of those who had tried minimalist running shoes reported they had experienced an injury or pain while using the shoes. The most common body part involved was the foot. Most (61%) of those reports involved a new injury or pain, 22% involved recurrences of old problems, and 18% were a combination of both old and new musculoskeletal problems.  More than two thirds (69%) of those who had tried minimally shod running said they were still using minimalist running shoes at the time of the survey, but nearly half of those who had stopped said they did so because of an injury or pain. The most common sites of pain or injury that caused survey participants to discontinue minimally shod running were the foot (56%) and the leg (44%).  While some runners who tried minimalist running shoes suffered some pain and discomfort, a greater percentage (54%) said they had pain that improved after making the switch. The anatomical area most often associated with improvement was the knee. The results were published in the August issue of PM&R.”

Look at your patients and clients shoes!

Can you see the varus cant to the heel counter of these shoes? This is an Asics  Gel  Kayano; a shoe we seem to see manufacturers defects in frequently. This could be a good thing for an overpronator, but could be a bad thing for a supinator. With a drop ( ramp delta) of 13 mm, and a narrow toe box, we are not huge fans…
