Hey Lulu; I don't have my new Cathe videos yet, but I did complete a rotation of 'Insanity' (loved it!). To be honest, they say to wear cross trainers (I have Nike Sparq?), but I loved the feeling of doing it in my Nike runners (more cushioning). Also, I love my new Nike Free Runs --- very light and supportive. It may be a personal choice for you as all the jumping does require some nice cushioning.
