Do we have any promising technologies for walking in VR?

A place to discuss any and all things Virtual Reality. This is the main VR problem that I’m waiting to be solved. We seem primarily limited to teleportation, room-scale experiences, walking with joysticks, and expensive treadmills. All of which kinda breaks immersion for me. Once we can realistically replicate walking in VR, it’s gonna be next level. Does anyone know of any promising technologies for walking in VR?
