Abstract
A core for incorporation into a gliding board, such as a snowboard. The core includes longitudinal and transverse core segments with long grain configurations that are combined to adjust the edge hold and maneuverability of the board to accommodate particular riding characteristics. The core segments include anisotropic structures that are oriented relative to the orthogonal axes of the board to achieve the desired core characteristics. The transverse core segments are located along the side edges of the core and oriented to tune to the core edges for a particular edge hold and overall board maneuverability.
