Hi Everyone,
I have just started running again after a few years of getting fat and I am really hurting with shin pain. I have tried heaps of shoes and the other day I found some orthotics that a guy at Nth Syd made for me a few years ago. I wacked them in and pain is gone

Good to hear that you have started running & the old orthotics have resolved your shin pain.

My drama however is that they are very hard under my feet and causing blisters, also they dont seem to fit properly in shoes at the heal area, my foot is quite high in the shoe and my heal feels like it is coming out of the shoe when I run again causing blisters.
Does anyone have any ideas, my Adidas Respone shoes are ok but the Kayanos and structures are terrible. Can you get orthotics that are not hard ?
Please help I really want to keep running, I made 40k last week !!!
Where exactly are the blisters occurring? (i.e. in arch region &/or heel?).
I prefer to characterise an orthotic, not by its 'hardness' but by its flexibility. The flex of the device is the important functional aspect of the orthotic (apart from the degree of correction) as opposed to 'hardness', as some 'hard' materials flex very well & some 'soft' materials don't flex that much due to the density/thickness used.
I believe that orthotics should be of a semi-flex variety as the foot was designed to flex as to adapt to the contours of the ground as well as absorb shock. Thus a corrective device should be of a similar nature. It thus sounds like your orthotics could be rigid in nature & your foot is having to 'flex' on an unforgiving rigid device thus directing stress on the skin i.e. of arch area... thus contributing to the blisters.
You can get custom made orthotics with semi-flex characteristics that can fit into a variety of shoes - particularly running shoes. It can be a bit difficult however getting an adequate fit into a variety of women's footwear due to the large variety of styles some women wear i.e. court styles.
Sometimes adjustments can be made to orthotics so they fit better into shoes i.e. if the orthotic isn't fitting into the heel cup of your shoes then one could grind some of the width of the orthotic so it sits better in the shoe.
If the orthotics are now not appropriate (despite resolving your shin pain) then you may need a new pair which may be now more appropriate for the long term - particularly now that you have started running.
One other point: By the fact you said that you "found" these orthotics tells me you hadn't been wearing them up until recently. Were you running at the time when you were assessed for the orthotics? Have you then 'broke them in' again? (i.e. walk in them, increasing the amount of time you wore them so the feet & body gradually adapts to this new corrected position.) If not, & you just went running in them, then it is very likely you could get blisters. Also the footwear themselves need to mould/form according to the orthotic & the new foot position in the shoe. Thus if you didn't go through the 'break-in' period again, then I suggest you do so in which case the blister problem could resolve.
All the best.
