    I took a job as store manager at one of the top soccer retailers in Denver CO, Soccer Stop in Highlands Ranch just to get the opportunity to sell and make sports orthotics for increased sports performance. I did have success making a few devices for healthy players. One of my most appreciative players was a U14 US Soccer National Team starting midfield players. I only made a few pairs of sports orthotics for performance use using softer materials then I use to make alpine ski devices. I wanted to just control a bit of movements in the foot that don't seem to be needed.
    At first I thought that if you could make the foot better at edging during a quick turning motion you would improve overall performance related to fatigue and quickness of movements. I used and tested a number of custom made devices in my own soccer shoes first. I liked the feeling of a more stable platform under my foot while changing direction on well maintained fields (soft surface).
    I started to question that approach after playing on a poor fields that lacked softness in the surface.
    Many players use OTC devices and many are not correct at creating a neutral STJ position base. Not a lot of problems without a well positioned stance from those devices as far as I know??

    After 18 months I stopped even talking about custom made devices because too many of the speed, agility, coordination coaches kept sending me players with overuse injuries. I'm not a medically trained person and that was not my area. Also the age of the player I met with overuse injuries seemed to relate to their changes upon reaching puberty and it was just too complicated for me.
    Most all were growth plate issue related pain symptoms. Most all players and parents did not want to stop the activity to give the body a chance to catch up with the changes of growth or to allow time for the pain to go away. They wanted to how to stop the pain and also keep training. ?? I would tell them I was unaware of any methods to do that, that was not my area of experience, and that they should talk to their doctors/professional trainers about that.
    #1 Do no harm...
    I went back to the adult sports of alpine skiing, cycling and golf.

    Second point.
    I also started to question the use of supportive custom made devices in this type of sports application?
    When I looked at close up photos of the foot making a powerful/quick movement of a flat grass surface I saw what to me was a need for the foot to change shape to conform to the flat surface that is almost never right straight under COM. The foot is always planted way out laterally away from COM. The distance varies depending on the speed the player is moving forward and the new path that intend to change to. The need of the foot to roll and flatten to match the shape of the surface became something I needed to understand better??
    Q- was the edging support even a right approach for running at speed and changing directions on a soft surface?

    Contrast that to my experiences as a alpine ski boot fitter who makes devices for sports where we also use the foot in aggressive edging/balancing actions that are far away from our COM but use the foot primarily in a edging and balancing position and I became more confused about the use of a custom made neutral position supportive device for soccer/football players.
    I do know many of the top players do use custom made devices. CR7 Real Madrid is said to use a thin carbon device in his shoes.

    Just adding some of my own personal experience info to your discussion about orthotics and their use for soccer players and their sport related injuries.

    I use a French made Sidas HD Vac system for making custom sports devices. I use different types of blanks depending on the intended use.
    Some I use with a neutral posting material (EVAs) under the device to create a better and more stable interface with the shoe, but not always.
    The stiffness of the device is dependent of the type of action and movement control I'm looking to achieve with the device's use, and/or want to allow to happen naturally. That's not an easy area to figure out?? It happens mostly with a judgement call based on the sport's biomechanic movements involved, the foot type observed, and the type of shoe involved and the type of surface the foot will come in contact with during use. *Not a lot of material to find on some of those interrelated topics.

    I'm not currently medically trained but have worked under a few C-Peds, and have worked at many of the top alpine ski retailers in the US as well as the ski shop where Superfeet products were developed in Mammoth Lakes CA.
    I have over the years, and do currently study most of the current materials out there related to the use of neutral molded sports performance orthotic devices. I have studied many medical related books also. I'm also about to formally train and take the C-Ped exam myself in the next year after working under a third C-Ped run store/lab that fills RX for doctors.

    Nice reply, thanks.

    The following comments apply to adult players only.
    Part of the problem (I found) was that soccer players at speed, like their sprinter counterparts, weightbear mostly on their forefoot, rendering rearfoot control obsolete.
    Of course I could go on and on about how orthotics are fitted to soccer boots which leave little room for the foot, or how Premiership players in the UK are not keen on orthotics - because they like their boots to be tight as they are, for better "feel" and "control".

    There is no one-fit orthotic for soccer. For frontal plane control a forefoot post on a soft device made to fit the boot AND the foot can work well in some instances. For pre-season forefoot blistering the same type of device works well.
    A successful modus operandi is to cast the foot as normal. Use the positive cast to make a thin EVA device - post the forefoot valgus or varus, in mm or degrees - then add padding as needed. Then strip the inside of the boot and throw it away. Replace inside of boot with the orthotic, suitably trimmed to fit, and ensuring that the device approximates the thickness of the original innersole. Cover with nice leather (blue for Birmingham, red for Liverpool).

    I saw several players in whom the need to see a podiatrist was less to do with my clinical work, and more to do with being able to justify invasive treatment and/or surgery. The "yes, he's tried everything, and nothing worked" syndrome. One particular case was justifying ESWT for plantar fasciosis. The podiatrist was finally called in, but way too late. The club doc owned the machine.....

    And I know of one particularly high-profile Premiership club whose first team players all had two pairs of orthotics for their boots. I used the same lab at the time, and I know that those "soccer" orthotics could never fit into a soccer boot and allow the foot to fit in comfortably.
    That was not that long ago - I like to think things have changed for the better in UK soccer injury management.

    It's really not that hard to fit them into a soccer shoe. Even tight ones.
    As I said, most shops now sell OTC devices and those can also fit into the most all of the new shoes.

    Yes, you want the shoes tight but not so tight they will cause blistering (#1-friction, #2-movement, and #3-moisture) and also not so tight that they over compress the forefoot which needs to splay just a bit for good balance. Lots of old info still out there about how the newer shoes are to be initially fit. We have some shoes that are still real leather and those will stretch. Those shoes are best for odly shaped feet. But many normal foot shapes and normal functioning feet can be fit nicely into a synthetic material shoe that will not stretch with use, and as so does not need to be fit overly tight to start with. You don't really need to overcompress the foot in a soccer shoe. You want feel through the shoe and you want a bit of shock absorption by letting the foot move a bit and allowing the foot functions to work they way they were intended to as you run, stop, and change directions quickly.
    The tight as you can get them is an old myth that came from a time when just about shoes were made from leather and they would grow bigger with use espically after getting wet (England) A current synthetic performance shoe fit when too tight or too small just produces unhappy players with too many blisters to do "the work" of the game.

    CR7 is Christiano Ronaldo of Real Madrid. Custom devices are used very often by players who get to play on professionally maintained (soft) fields. I have made them for pro level players. I have also talked to quite a few pro players about their use at the pro level.
    It differs for youth players, many youth fields are not kept soft where edging with the shoe would be the most useful.

    The blanks I use are the same thickness, or if I chose even thinner than the stock insoles that come out of most good shoes these days.
    The exception is the indoor shoe which because of the surface usually has a glued in stock insole. That can also be removed using a little bit of heat and a flat scrapping bar.

    The question I would like someone in the medical field is:
    Can the foot edge while attempting to turn quickly and still be injury free?

    If you are involved in making sports products and have not looked through what Sidas is currently offering through their medical division, you might find some very interesting new products now.
    Look at their international catalog.
    * I'm not a salesmen and I don't work for them.
    The direct foot negative molding system - Sidas HD Vac system is currently the best in the world.
    Why the medical industry still used a casting and vacuum method is a bit confusing to some of us in the sports world??

    This HD Vac creates a negative mold which can be minulipited if needed.
    The negative mold can be made with no weight, semi weighted, or full weighted and then corrected back to a neutral position if that what you want.
    A negative mold can be made, the device molded, and the device finished in under 45 minutes by a well trained person.

    I no longer work in professional football. I can tell you that as of seven years ago the "myth" of tight boots = better boots was alive and well in five of the top professional soccer clubs in the UK - probably more - those were just the ones I worked with.

    Plaster casting for a foot impression is good for one-offs. I'll take your word about the SIDAS system - I assume that's for volume casting since it must come with a price tag (either up-front, or built into each pair of orthotics).

    On your question about a foot edging whilst turning.
    I'm sure a player can edge their foot whilst turning without injury. Fatigue will play a part, of course, in the probability of injury, as will COP, and what the contralateral limb is doing. Thinking about this, the intention of the player is important too. Is he about to tackle, just been tackled, or is he going for a high ball. Or she, of course.

    Big question. I don't think there is a simple answer, I'm afraid.
