Train like LeBron in the NIKE LeBron TR 1 – versatile men's training shoes built for a range of workouts. Large lugs on the outsole combined with a Waffle herringbone pattern work together for traction on most surfaces. A foam midsole cushions against repeated impacts, cables at the laces provide a secure fit, and flex grooves on the heel and forefoot improve agility through natural strides and quick changes of direction.
