Sorry... "N0311" --
I need to move the heel piece back slightly... and can't figure-out how to do it. I just moved some Salomon 900's a slight tad -- and it was easy (lift-up on the tab with a screwdriver and slide the heel piece). But the N0311's have me stumped. There's the big phillips (DIN) and then there is an odd-shaped "round-ish something-or-other" with an engraved "arrow" on it -- that would seem to be the ticket (if it is designed similar to the Salomon). But I don't think that's it. Hmmmm. Any help would be appreciated.
