The Karada ni Ii Iwa ("Good for the Body Rocks") are reflexology sandals designed to intensely stimulate the soles of the feet using textures inspired by real rocks.

Unlike classic massage sandals, their specially positioned nubs target the main pressure points of the foot while conforming to the arch for a more complete and intense stimulation. The adjustable strap allows for easy adjustment of the fit to suit individual foot shapes.

Recommended for people seeking a pronounced foot massage sensation at home or after a long day on their feet.
