Abstract
An improved foot piece for use with a surfboard type water craft that has a flat top surface which is equipped with a loop bearing surface component having a generally planar outwardly and upwardly facing surface portion with a multitude of small, closely spaced, flexible loop elements has one or more flat flexible surface components with an outwardly facing surface portion that is equipped with a multitude of small, stiff, closely spaced and outwardly projecting linear elements. The flexible surface components are fixed to the outside surface of the foot piece, preferably to both the bottom and side surface portions that underlie the sole and are at the instep side of a user's foot in the foot piece. The linear elements become engaged by the loop elements when the generally planar surface portion bears against the outwardly facing surface portion of the flexible components so that movements of the foot piece in parallel with the top surface is resisted whereas withdrawal of the foot piece from the top surface of the surfboard is not resisted.
