I like a lot of the boots on that site, and I'd happily pick up the feet for them, but then my concern would be that the ankle peg would not fit the MOS leg. Working with the MOS Body is a challenge because it was created custom for this one figure (after the Schwarzenegger body was scrapped) so finding items made for standard TT fare is tougher than I'd like it to be...
Normal TT pegs work on the MOS body.
