Working with 2x Ironman World Champion Tim DeBoom, the Pearl Izumi EM Tri N2 was built to meet the harsh demands of Kona-style races. The long course model, this men's running shoe features a seamless synthetic and dual-layer mesh upper that uses bonded technology for structure and durability, leaving the inside of the upper smooth and comfortable against your foot for sockless race-day. Motion midsole promotes an efficient turnover running style. Dynamic Offset technology eliminates forefoot slap and reduces shock.
