Marek,

My feet supronate badly (over 45 degrees) and when paddling the ankle bones
are pressed against the hull. Since this is fairly uncomfortable after long
paddles, I placed a thin sheet of insulating foam (the kind that go under
your sleeping bag) beneath my ankles. When it wears out, I just replace the
foam (it is pretty clear to me when this happens - painful reminders are
very effective). That I was protecting the hull in this way wasn't something
I considered, but whatever works.

If you don't have my anatomical quirks, you might choose a material that is
a bit tougher.

I've posted a couple of entries to my weblog from paddling local rivers in
northern Colorado, the Poudre and Big Thomson, after returning from Texas
Water Safari.

During my second paddling on Big T, I noticed with a surprise that my
Sisson Nucleus kayak was taking water! And I didn't hit any rocks or logs
