Rewind: Walking gait in a pencil skirt

Gait Pathomechanics: Walking in a Pencil Skirt.

We wrote this piece 5 years ago. We are updating it with a new disasterous video. Speed ahead to the 30 second mark to get to the good stuff. The Gait stuff.
No longer can there be adequate use of the obliquity of the pelvis and thus abdominals or contralateral leg swing to initiate supination and toe off and . . .

Knee flexion in gait loading. Heeled shoes do things.

Watch this video, you have likely seen it already but did you notice it ? You will have to fast forward to 1:40 to see the video that applies to this screenshot here today.
How much knee flexion should occur during the initial loading response ? In this walking gait video, if you look closely enough, her high heeled shoes are forcing her to load in a what is technically a midfoot stride (because of the high heel) when in fact she is truly loading initially in a forefoot load, ie. plantarflexion. This abrupt load is forcing her to dampen the load with a quadriceps eccentric (if you watch closely enough, the knee flexes every time during loading, more than it should). Normally, in flat-er shoes, this knee eccentric is basically hidden (it is almost an isometric), it should never be this obvious unless one's quads are truly too weak. To be fair, the shoes are propping her into anterior pelvis tilt, as these high heeled shoes always do, which promotes lower abdominal challenges and premature quad loading, and delayed glute loading (don't believe us? stand up, dump into an anterior pelvic tilt and increased lordosis and try to engage your glutes. Nadda ! So the loading shifts into the quads).
Welcome to another ramification of high heeled shoes, again.
Admittedly, this lady does a great job. Her belt line stays pretty neutral and doesn't dip on each loading response and she is in good control. Ivo and Shawn on the other hand are terrible in their pumps :)

Sprinters, and those who forefoot load during running, are you surprised with anterior knee pain when it comes on, or achilles pain or calf tightness when the calf fatigues and can no longer hold you in adequate plantarflexion ? How about low back pain or tightness after runs ? No, you should not be surprised is the correct answer (unless you have enough durability in the quad and calf, and lower abdominals to sustain the length of your workouts, over and over and over.

Why you should have a picture similar to this of Sandra Bullock in your shoe store….  Because of the story it tells to all runners (and walkers)….. we guess that means everyone then doesn’t it ?   
 Note what the lovely Sandra is wearing. 
 Your eyes may be first drawn to the accentuation of her buttocks and calf as well as her lifted chest.  In actual fact, that is what high heel shoes are designed to do. 
 What you might not see because you are drunk on her beauty and figure is the cost on her body from those illusion driving high heel shoes. Here is what they are doing behind the scenes: 
  creating a perpetually plantarflexed foot with excessive and unnatural forefoot loading and likely increased use of long toe flexors 
 sustaining tension in her quadriceps because she is purchased forward on the balls of her feet 
 hyperextension loading the knees with increased lumbar lordosis which is making it a challenge to maintain adequate abdominal tone, in fact, likely inhibiting the abdominals.   
  Who cares right ? It all frame her glutes nicely and accentuates her bosom right ?  
 Blame it on Sex and the City or blame it on men who like to see women in high heels, but there is blame to dish out. 
 Put Sandra in some Newtons or Altra’s ……or some other zero-drop minimalist shoes and watch: 
  Her heels drop redistributing normal rear : forefoot loading  
 Foot intrinsic muscles begin to re-engage as the long toe flexors settle down now that she is off the forefoot 
 Achilles and calf muscles lengthen to their normal state 
 Tone normalizes in anterior shin compartment and toe extensors 
 The foot mechanics we were born with are restored because they are in the environment we were born with…… that being that the forefoot and rearfoot are both on the same plane (flat on the ground) and thus the mechanics they were designed to engage are once again available and possible.  (But it will take time to restore the lost function. Even men’s every day shoes, including traditional running shoe trainers have a ramp-delta heel lift.) 
 Lumbar spine lordosis reduces, abdominals engage easier 
 Psoas returns to normal length from its shortened state 
 Cervical spine returns to neutral 
 patellofemoral joints compressively unloads making for some happy knees 
 Gluteals re-engage and take the extension from the lumbar spine and put it back into the hips where it is supposed to be achieved. 
  And that my friends, is why you need a picture of Sandra Bullock in your shoe store now that you know what heeled shoes are doing in the background of your body mechanics. 
   Bammmmm…….. The Gait Guys…….. critics of even the most beautiful actresses in Hollywood.  Ivo and Shawn…….risking it all, even a dinner date with Sandra, to bring you the facts.  Our only question now is, “Why Jessie James? Why ?”
