To your question, if a bruised foot is going to give you problems it
will normally be demonstrated by a positive hoof-tester response or some
degree of lameness. So if both are negative, saddle-up. Try to avoid
hard-pack surfaced, maximum effort extension/foot strikes and agressive
down hill work.
There is a chance that an absess will form, or the bruise will be
aggravated, but again, a positive hoof-tester response or some degree of
lameness should be apparent. The option is a full lay-up without knowing
for sure if it's warranted. In other words there is a trade-off between
losing condition and healing. Just be VERY sensitive to the
situation.
We would also consider padding using Jim Bumgardner's "star-cut" method
rather than something under the pad like silicone. If your not familiar
with the star-cut it goes something like this. Before nailing the
pad/shoe on, cut a peace sign into the middle of the pad starting at the
heel. Stop the arms of the sign/cut about 1/2" before the pad dives
under the shoe. Nothing goes under the pad. The flaps of the cut can
be lifted to clean soak and dress the sole as needed.
See ya,
