Arabica, my DS has Hypermobility Syndrome and low muscle tone. His feet started to turn under and his ankles and knees got closer together over a few weeks in the summer when he was 2. Because he was wearing shorts it was very noticeable and by the end of the summer he was walking very strangely, on the sides of his feet. He had only just started walking independantly and it was as though his legs couldn't take the strain. When he finally saw a specialist rhuematologist at 4, the damage was done and his feet/ankles/knees will never be the same again (that makes it sound as though I did nothing, but GP refused referrals/HV said all was fine/consultant was a wally/etc, etc).
He now has to wear Piedro boots and orthotics, and always will. DS's three smaller toes on each foot are curved and are rotated outwards, which the lovely orthotics man we see has assured me will be helped by the boots, and isn't really a problem - yet, but is caused by the bones in his feet being hypermobile. Also, his little fingers are curved.
DD1 also HMS and in Piedros and orthotics because her feet turn outwards (she had to be different ). Boots are lovely, really nice, much better than I thought they would be.
But, try not to get fobbed off like I was...it took me 3 years to get DS's feet sorted, and had to beg paed. to get DD1 seen by podiatry. And as Phoenix says, waiting list are long...and then you also have to wait for the boots to be ordered in, and then another appointment for fitting, so it all takes ages, but is really worth fighting for. DS can now stand on one leg for 6 seconds with his boots/orthotics on......doesn't sound like much, but considering he can't do it at all without boots, it is pretty impressive!!
