I, Dd and Ds have varying degrees of hypermobility, none of us too bad. We also all have feet that pronate. Ds is the bendiest of us all and has the oddest feet. I have had problems with being hypermobile. Nothing awful, but I'd like the DC to avoid the problems I had as a teen and young adult, so I took them to the GP.
GP told me to buy paediatric orthotics online and said Orthaheel is good. I went away and looked them up but the choice was vast. Then I managed to get a free appointment with a podiatrist. He said dd doesn't need orthotics but advised on which type of shoes to buy. Ds definitely would benefit from some. He said to buy Vasyli, 3/4 in red, then to buy carboflex inserts when Ds is about 16 (he's currently 7).
So, once again I went off and looked it up. Vasyli are really hard to get hold of! I want to get some before we get school shoes.
Where do you get yours from? GP won't refer us because he is crap low-intervention.
