Baseball pants for my team and the coaching staff. When it warms up some and we have made it through certain portions of practice, once in a while I let them take the pants off. I can't speak for others but in my practices, players are running and sliding throughout the practice. For example, I threw BP off of the rubber. After you have hit, you join a very small (approximately 3) players who are at 1st working on reading my move either to the base or plate and breaking. The hitter is hitting. Then, we go live. I throw it like a real game and we have a catcher. When we go live, we have players stop fielding drills at their positions and play live. I expect that player to try to steal if I give them the sign and I expect for them to slide if they have to. On hit and runs, I expect that player at 1st to break on the pitch and play it live.
