Stands are available at most audio outlets. The mark of good bookshelf speakers and stands are high weight. So, for a good speaker, you are talking 20+ pounds. For a high quality stand, high also. If you want to maximize the sound quality one should fill the stand with steel shot (in the old days it was lead shot). So together… you are talking about 40 or fifty pounds. So unless you are playing football 🏈 in your audio room there is no chance they are going to tip or be knocked off. I use vibrapods between my speaker and stands to decouple them from floor vibrations, and they are soft elastomer, so slipping is prohibited.
