TxAg, if the quiver is properly made of leather that is pliable enough to mold to your back and it hangs at the correct angle, the arrows will not make any noise at all. And you do not need a bunch of filler stuff and oats in the bottom and wool and fleece lining to have a quiet quiver. These things are so simple and effective, but it seems like most of them sold today are not made by hunters who know what constitutes a good quiver but are sold on looks, leather carvings, etc.
I do not use foam in the bottom of my quivers, just a piece of carpet cut to the size to fit snugly in the bottom. The points hold sufficiently in that not to move around--no booties, nothing else needed.
