Yes, you can wear flip-flops at Disney's Typhoon Lagoon, but they are primarily for walking between attractions rather than wearing on the rides. Disney strongly recommends wearing some form of footwear, like flip-flops or water shoes, because the Florida sun can make the concrete walkways and sand dangerously hot, leading to burned feet. However, for most body slides (like Humunga Kowabunga) or the raft rides, lifeguards will typically ask you to remove your flip-flops and hold them in your hands or leave them at the ride entrance. If you want footwear that you can wear throughout the entire experience, including inside the pools and on most slides, water shoes (without metal buckles or zippers) are the better choice. Many guests prefer to wear their flip-flops to the "edge" of the wave pool or the entrance of a slide and leave them in the designated cubbies or shoe racks, though keep in mind that they are not monitored, so most people stick to basic, recognizable pairs to avoid mix-ups.
