Thanks for the feedback. Seems like they are going to be harder to get than I assumed, the only Bont dealer around says they can't get the track shoe as their US distributor doesn't carry them (not sure if it was a can't or won't situation).
Anyone buy directly from Bont's website? I tried on a pair of Bonts and have a pretty good guess at size, they seem to fit a little big (about half to a full size bigger than SIDI, but maybe its because they are moldable?). Only worry is getting hit with duties, its like 30%...
