I'm like MHFQ, I do the half tuck around the house.
When we were in TX it seemed more acceptable to tuck your pants into your boots. A lot of them guys spent a good pile of money on some custom boots with fancy tops. The working guys did it and you even see it at the cutting horse futurity.
Someone mentioned above about it being hard to do with boot cut jeans....
You have to fold the bottoms over like if you were going to "peg" them, then fold up the bottom hem once to make a cuff. How big the cuff is depends on the length of the jeans. You don't want all that pant rubbing on your ankle bone jammed into your boot.
But I wouldn't do it here, not very acceptable.
