The FLOPEDS "P3” Princess is the T3 with the row of 8 stones on the strap, it is a new generation of flip flop, after our success with the "Laguna Series", we believe it was time to do some research, and to develop a product that would offer a little more support and control, than that provided in the Laguna. The "P3” is also a lot more sturdier build, and looks great on any foot type. If you are using an orthotic or insole, you have got to try the FLOPEDS - P3 although no flip flop can come close to a custom built orthotic, we believe this is the next best solution.
