The ideas kept coming, so Callaway put in more moment of inertia (MOI) and lowered the center of gravity (CG) even more by redesigning the head shape and improving the Internal Standing Wave. It's amazing what you can do when you change everything.
The Callaway Lady XR Iron is an iron built for speed. Callaway took the Cup 360 that redefined ball speed in fairway woods and brought it to irons. The improved Cup 360 acts like a spring on shots hit low on the face and increases ball speeds everywhere else on the face, too.
The distance is incredible, and that's just the start. When you factor in the lower center of gravity (CG), all that forgiveness, and the face flex of the Internal Standing Wave, along with the precise two-piece, dual-heat construction, you can see why Callaway wanted to get these irons in golfers' hands right now. They're looking forward to redefining the iron category, again.
