If you are having trouble with players overstriding I recommend building stride boxes using 2x4s. the inside of the box should be no longer than their bat as well as the stride should not be longer than the bat. We build a 32 inch, 33 inch and 34 inch stride box and use it during our soft toss station. The front foot hits the front of the box and it causes the players to shorten the stride. Good when hitting in doors.
