left ankle rolls inward while skating

Question
I am 56 year old female who has been  roller blading for 7 years.  I have noticed my left ankle tends to lean inwards.  I don't have the manual for my skates,  But I have been told that there is a way to correct this.  I have noticed that there are  "2 screw in the bottom of my boot and it looks like they would slide from one side to the other.  WOuld this be the way to correct my problem?  I have Rollerblade Training Skates.  EVO 07  If that helps.
Also, are there certain wheels that are to be used on a bike trail?  My friend bought new skates and her shins hurt her terrible.  Tried them out several times.  She also has been  roller blading for 7 years.  She didn't have trouble with her older ones.  We figured out that it might be her boot type.  Her older ones were the hard plastic which gave her more support.  WOuld that be the difference?

Thank you

Answer
Hi Vickie,
  Normally when an ankle turns in it's because your feet are too far apart.  If you bring your feet closer and make the effort to stay straight up on the wheels that will help to create a new habit.

  If you have been skating this way for quite a while (depending what your boot is made of) the boot may have conformed to the ankle leaning inward.  If the boot is made of a hard plastic it will not conform......if it's a fabric it will conform.

  The plate that is mounted to the boot is mounted in a certain place for accuracy of balance and roll.  I have never heard of moving it over to correct an ankle leaning inward.  I could be wrong but I don't think that's  wise thing to do.

  If you try keeping your feet closer together and that still doesn't work......you may want to consider purchasing an orthotic arch support.  You could very well have one ankle that is weaker than the other.

  As far as your friends skates hurting her shins?   That's usually because the boot is either higher or harder than what her shins are use to.  She can try loosening the top so she can bend her knees more and perhaps put some kind of foam cushion between her shin and the tongue of the boot.  Hopefully once the skate is broken in a little more that will resolve the problem.

  There are many different types of wheels for inline skates.  For outdoor use you want a little softer wheel because of the pebbles, twigs etc that you find on bike trails.  If the trail is a hard clean surface then you can go with a harder wheel which will give you an easier, faster roll, where the softer wheel tends to make you work a little harder.

  I hope this information helps.  If you have any further questions, feel free to write again.
