Finish your last rep with power and rack it with a roar that stuns the gym floor in the Nike Air Max Alpha Trainer 5. Max Air cushioning offers comfortable stability for lifting whether it's a light or heavy day. A wide, flat base gives you enhanced stability and grip for all kinds of tough workouts without sacrificing style, as you roam from station to station and set to set. Cushioned for Comfort A foam midsole with a Max Air unit at the heel cushions your foot for comfort that lasts. The foam collar pads your ankle from 1 move to the next. Sturdy Foundation The flat, wide sole with an enhanced rubber tread pattern gives you stability and traction. Rubber wraps up the side to keep your foot firmly on the sole during lateral movement. Flex grooves in the forefoot are designed for lunges.
