Multiple offloading modalities are currently used in the management of diabetic plantar foot ulcerations. A relatively new device, the Rocker Insole, was tested for its ability to relieve plantar forefoot pressures when inserted into a surgical boot as compared to a patient’s customary footwear and the surgical boot alone. The Rocker Insole significantly reduced forefoot pressures by 48% when worn inside the surgical boot. Mean peak pressures unexpectedly increased 12% when the surgical boot was worn alone. This preliminary investigation suggests that when worn in conjunction with a surgical boot, the Rocker Insole can effectively offload plantar forefoot pressures and may be useful in the management of plantar metatarsal ulcerations.
