I'm not really the kind of a shoe nerd who has a different pair of shoes for every scenario, but I like to use different shoes for sport and bouldering. For sport, especially for multi-pitch, something comfortable, with stiff sole and laces. Katana is very good and comfortable, and I liked the pink Anasazis a lot. For bouldering something tighter with velcros. Especially the heel cup has to be tight or heel hooks won't work. My current favorite is Theory.
