Abstract: A foot brace system for use in a kayak or similar water craft. The system includes a footrest for engaging both feet of a user, and can retract and extend laterally so as to permit the system to account for variations in the beam of the craft when the footrest is moved fore or aft. The tilt angle and height of the footrest from the floor of the craft can also be adjusted. The system includes a pair of rails which are connected to the footrest via a sliding connection. The fore and aft position of the footrest is locked by a rope and cleat.
