AND AROUND THE FEET, NOTHING?



A very experienced marathon runner once said that nothing could be more important than not having problems with the shoelaces. 


Advisable was tying the shoes with double laces; one on top of the other. 


Until that date, our laces would get undone as we walked at least sometimes, and that was certainly a hazard.



A very experienced and caring mother once said that nothing could deform the feet more than shoes that were not of our size, like bigger or smaller. 


Her words had to do with the shape of our feet, but the advice is also superbly important for people who run because those need to literally command their own feet to maximum degree allowed when running.


Runners must wear shoes that are not bigger or smaller than their size, so that they don't lose power (the larger the difference, the smaller the control we have over our own feet). 


Australia was a fortunate Country for size of shoes in 2001: We here had ½ sizes, so that a person who was not precisely size nine could find shoes with perfect fit (9 ½ sizes, for instance). 


Australia now has some manufacturers that have even four variations of sizes in the same unit interval (Diana Ferrari, for instance), but has lost a lot of its half sizes for some reason (2013). 


In having difficulties with finding a shoe that fits our feet perfectly well, we can always go for a shoe maker...



A running shoe cannot be like an old Japanese-style women’s shoe, meaning hard as a rock (they were literally made of wood). 


We do not want to feel like the Japanese ladies from ancient times when running or walking: As if we were carrying a log.


Our shoe also cannot be so flexible that we feel the ground under our feet as we walk or run because that would make us feel the impact of anything on the ground, say a piece of glass, a little pebble, and alike.



A running shoe is a huge investment, so that it would be better if it could last. Shoes that are made of natural fibers would have to last for shorter than those that are made of synthetic material, especially created to satisfy our scientifically identified needs.  In this way, nylon would be good. We also would like them to stand water, since at least sometimes we have to step inside of pools. Thus, it would be nice if they were waterproof.


As for how much heel we should have, or how much diagonal lift, this is a bit of a mystery. 


There are tribes of blacks that are well known for being best long-distance runners, and they run barefoot. 


In this way, a running shoe with no heel looks all right.


On the other hand, blacks that run really fast and win races at the Olympic Games wear running shoes and even advertise specific brands sometimes...


Australia recently had a fun run in Melbourne, where women would be running a race with heels, like social heels. 


That should be considered medically insane because we would injure our spine to maximum if running with heels that go above a certain height or that escape the traditional shape of heels by too much. 


Also, any accident when running could lead to much more serious consequences to our bodies if we are wearing heels, especially the so-called wedges, which, for even normal walking, are inadvisable. 


A running shoe should support our feet to maximum so that we feel comfortable but in control of every single piece of our feet to maximum that we can be. 


It seems that catwalk people have to practice quite a lot to walk in the way they do (using the tip of their feet), so that that cannot be a natural thing for humans. 


That does not mean that a person who runs in that way would run slower than a person who runs with flat feet. 


We do not seem to have scientific testing that be reliable to assert anything in that area. 



The fastest animal on land seem to be the cheetah (http://uk.answers.yahoo.com/question/index?qid=20090903090530AAokyLZ and https://www.youtube.com/watch?v=KIeXEiJuJUY) and, if we observe it running, we reach the conclusion that it lifts its entire body in the air and uses the front paws to give the kick and the back paws to simply complete the movement, in a way not to drag the back paws, but to supplement the movement (notice that the body remains in the same sort of disposition). 


We also notice that it goes with the entire paw, like no tip first. In thinking about it, any lift we impose to our feet (heel) should make us lose balance and control over our feet, so that the best shoes for running should be flat and close to the ground, certainly contradicting our intuition and current marketing sale-points in that sector. 


The cheetah has full contact with the ground... 



According to Rodney Southern (http://voices.yahoo.com/humans-versus-animal-kingdom-faster-678669.html), there is no way we, humans, can beat not even the bears (which would have to be really slow, given their immense weight, amount of fat, and body proportions) in a race. 


On the other hand, horses seem to be pretty fast and, according to http://message.snopes.com/showthread.php?t=61328, we can at least sometimes run faster. 



Intuitively, the less we feel the ground below us, the harder it is for us to keep control of our pace. 


However, if we are beating horses with our modern race shoes, then there should be some gain to diagonal lift and soft padding, which should diminish our perception of the ground, but, if uniform, could, after we get used to it, allow for running making less effort, therefore for better performance.   



Each time we hit our heel against the ground, we create a certain amount of discomfort for our skeleton, which may translate into injury or depreciation. 


This has to do with capability of doing the sport for a long time. 


In those regards, there are no doubts that the soft padding and the lift could only be helping. 


If we attenuate the impact on the skeleton of our pace, then we should be keeping it healthy for longer. 


By artificially transferring the work to our toes through the diagonal lift, we are certainly saving spine and skeleton. 


On the other hand, our effort to run will be increased of a certain factor, which might not interest us. It is all about how much it is worth winning... 



Some people die for trying to beat the record of car jumping on a motorcycle, and think that the glory of the achievement is worth the risks. 


The truth is that it suffices that they change the rules of the game in a way that everyone gets to be obliged to run with shoes that have diagonal lift and soft padding that everyone can be both healthy and winner in the races we praise in human kind at the moment. 



Nothing wrong with that, since nobody can play without protective equipment in an American Football game...   



Now, how much diagonal lift is acceptable, like where do we draw the line splitting healthy from harmful in terms of running? 


We do not have a general rule, since it all depends on the body of each one of us (size, proportions, type, and etc.). 


We can tell straight away, however, the height of lift and the shape that are unacceptable. Also the padding.



Our bones, muscles, and veins are connected in a very special way also in our feet. 


We must observe them for long if we want to really do the proper thing. 


We do not want to do the following: Interrupt blood flow, force our bones to uncomfortable positions, and make pressure over our muscles, pressure of any sort (we want to simply support them). 


We may wish to put pressure on our tendons when we have an injury already. 


In this case, the pressure may help us run and prevent worsening of the injury. 



The color of the running shoe matters too because colors are scientifically known to influence our mood and we want to avoid any induction to depression, laziness, and alike. 


In this sense, we should never choose black or white for our sports shoes since white picks all surrounding vibrations and black puts us down (if nothing else, it reminds us of death). 


Blue, red, yellow, and orange seem to be good picks in terms of colors (http://www.healthynewage.com/mood-ring-color-chart.htm). 



It seems that this subject is never ending, so that we will simply have to stop writing about it in order to have a blog (otherwise we may end up with a book!).
