The second offering from Lacoste's AG-LT line, the AG-LT23 Ultra takes a nod from its Grand Slam winning predecessors, the AG-LT21. The mid-foot ghillie system is upgraded with an improved fit and a more dynamic aesthetic, while the upper displays a totally new piqué weave which has been engineered for flexibility, strength, and breathability. The midsole features Lacoste's brand-new performance compound; LSRFoam, which is encapsulated beneath a transparent TPU forefoot cage. LSRFoam is made from Pebax pellets for a very lightweight feel and responsive result. The TPU forefoot cage extends into the midsole and exposes an internal midfoot shank which extends up and around the heel to support the players heel strike. Finally, the innovative LineGrip rubber outsole compound helps to ensure maximum grip and durability on all terrain.
