Callaway Golf announced Monday the launch of its Odyssey "S2S (Square 2 Square) Tri-Hot SB" putter, which combines a heel-shaft structure with zero-torque technology.
The new product features a more familiar heel-shaft design for golfers who find conventional center-shaft-based zero-torque putters uncomfortable. It maintains the natural setup and visual comfort characteristic of heel-shaft putters while delivering core performance.
The model adopts a single bend (SB) structure. It is designed to maintain zero-torque performance while positioning the shaft toward the heel. The design enables more intuitive alignment and a stable setup at address, reducing visual awkwardness and supporting a consistent stroke.
The head is made from multiple materials, with aluminum, steel, and more than 140 grams of tungsten strategically placed. More than 80% of the total weight is concentrated below the top line, achieving an ideal center of gravity and enhanced stability.
The face features an "Ai-Dual Insert" engineered with AI technology. The dual structure consists of a firm inner core and a soft outer layer, delivering consistent ball speed and a smooth feel at impact. The lineup includes four mallet-type models: Rossie, #7, Jailbird, and #7 Cruiser.
