A little followup on the foot peg adjustments - I tried your suggestions and
after a bit of experimenting, found a position that allowed my legs to be
almost straight, but still sufficient to allow me to brace when I needed to.
So far no more heel pain. However, now with my legs more straight, my
stomach muscles (such as they are) are complaining. I keep telling them
it'll be good for them!

Paddling with bent legs tends to work the hip flexors more and paddling
with straight legs uses the abs more. When I switch from my low volume
boats to a larger boat and have to paddle with bent knees, the pain in
my hip flexors is excrutiating.
