These are great for slamming on the ground I have them for my track athletes and weve broken a few medicine balls this season because they were not meant to be continually thrown onto the ground The kids like these; theyre grippy and dont bounce at all However you can tell there is a sand or gel substance that moves in them because if you shake it you can feel it move around I like this because it makes the ball a little unstable on the throw some people dont like that Just a heads up but if youre worried about wear and tear this is the ball for you
