NIKE SQ MACHSPEED IRONS with Steel Shafts Click Arrow to Select   LH 4-AW Steel Regular $379.95 LH SW 55° Steel Stiff $49.95             A radical new construction method combined with a hot, thin alloy face creates the fastest Nike iron ever. Faster ball speeds off the face means more distance. Speed = Distance: The combination of AM355 stainless alloy and an off-the-face weld construction creates a thinner, hotter face and wider sweet zone. This new construction offers an extremely hot center area, but also expands to lower on the face where the ball is more to be in contact. Stability = Forgiveness: The Nike PowerBow creates extreme deep CG. This provides a wider sweet spot and higher trajectory. Launch: The deep undercut repositions 50 grams of weight low and back to the Nike PowerBow for high launching shots that travel far and land softly.
