Honoring the original Air Trainer 1 legacy, Nike released the Metcon 2 'Metcon Knows' training shoe in July 2016. Dressed in the same Chlorophyll colorway as the 1987 AT1 worn by John McEnroe, the contemporary training shoe is crafted with a durable mesh upper and form-fitting Flywire cables to encourage range of motion for high-intensity training. Dual-density foam joins forces with a grooved outsole offering maximum support and traction underfoot for box jumps and other moves the gym demands.
