River & Curt...
You both make good points.
IMHO, base shoe is something that should be considered on a case by case basis.
By all means, baseboard should be installed après floor installation (if at all possible).
However, depending on just how irregular the subfloor or slab is, base shoe may be the lesser of two evils in getting a nice "finished" look at the elevations, rather than "caulking" or scribing a high profile base which won't bend enough to conform.
If it's GOT to be used, however, my preference is to keep it as small as possible and discreet/subtle. Ours is 1/2" x 5/8"... and painted on painted base, please.
I can't believe some of the monstrous 3/4" QUARTER ROUND some folks resort to.
Looks like someone laid a broom handle against the wall.
