Whats the difference between a cross trainer shoe & a running shoe?

i wanna buy one.Which one should i buy?Is RBK Pump a nice one?

Cross trainer is designed for it to be used while playing most sports...running shoes are made to be used while running/walking. The support the different shoes offer for the ankle and foot are much different. If you want a sneaker you can play basketball in, run in, and pretty much do an activity get a cross trainer. If you just want something for casual night our, something to look good, or you use just for running/walking get the running shoe.
