Thanks to those who recommended Steve at Pedal Pushers

He did a series of tests to see how my body was put together, and the
answer appears to be "the traction worked".
When I was about 6yo I had a close encounter of the unpleasant kind
with a trampoline and broke my left thigh bone. No, I don't know how
I managed it, but manage it I did! So there I was at 6 years old in
traction for 7 weeks over Christmas. Colour me unimpressed!
Anyway, I always thought the left leg was short if either of them was,
but it appears the traction worked so in fact it's a bit over 10mm
longer than the right.
I've developed a sort of twisted hunchback effect to compensate which
might explain the attraction to church steeples. Anyway...
The result is that somehow I need to compensate for this leg length
difference when I ride.
The simple test was a couple of bits of carpet tile under my feet
in the sandals and wooo! I can't describe the difference very well,
but riding is easier. Lots and lots easier. Easier so that my speed
has increased by enough to mean I was panting a lot more today on the
ride in than I have been for some time. I don't notice going faster,
the computer tells me I am and I'm definitely doing more work. I seem
to be doing it easier until I run out of breath!
I heartily recommend this service. I paid $165 for the hour it took,
someone on an upright bike would probably pay more as the job is much
more complex. But even if that's about as much as your bike costs, I
bet you'd end up being more comfortable and faster.
However, carpet tiles aren't the best solution.
I am using the sandals because I can't find shoes wide enough to fit
my feet, and adding 10mm of shim under the forefoot in the shoe isn't
going to make that any easier! Anyone have a line on shoes with
really really wide fittings? Shoes built for people with feet like
tennis rackets?
Another possiblity is to build up the pedal. I'm using SPD and MTB
shoes/cleats and Steve doesn't have shims for those. Anyone know of a
pedal that can be shimmed and be used with a shoe you can walk in?
The last possibility is to have a longer crank on the left side.
Sheldon Brown reckons this is a bad idea, anyone have any experience
with it?

- off to the podiatrist to see if it's possible to make a 10mm shim
to glue to the sandal.
