Stability: High: The more supportive the shoe, the more stability it can give to your stance. A combination of tuned support and intentionally placed cushioning helps you feel secure with every step. The heel Max Air unit has been fine-tuned for even better stability. The flat, wide sole with an optimal rubber tread pattern gives you stability and traction. Cushioning: High: Cushioning under the forefoot and heel helps soften the impact of your workout. A foam midsole with a Max Air unit at the heel cushions your foot for comfort that lasts. A foam collar pads your ankle from one move to the next. Flexibility: Moderate: The more flexibility that you have in the midsole and outsole, the more you can move naturally. Flex grooves in the forefoot are designed for lunges. Sticky Rubber: Rubber wraps up the side to help keep your foot firmly on the sole during lateral movement.
