Building off of the success of Odysseys Ai-ONE line, the Square 2 Square putters are constructed with a modern center shafted design to help players stay square through their stroke while minimizing face rotation. It includes the Ai-One Insert from the original line, featuring contours on the aluminum backer that is co-molded to a White Hot face to promote consistent ball speed across the face. Built-in forward shaft lean makes players set up with their hands in a forward press to reduce opening the face and keeps the face square through impact.
