An aerobic shoe is a special type of athletic footwear designed for high-intensity workouts. These shoes are made to provide maximum support and cushioning to the wearer's feet, which is essential during fat-burning and cardio-based workouts. There are a few other terms that come to mind when discussing aerobic shoes: gym shoes, workout shoes, running shoes, and cross-training shoes. However, while they are all athletic shoes purposefully designed to provide support and comfort during intense physical activity, they can differ slightly in their design and features. Regardless of what they're called, it's essential to choose the right aerobic shoe to prevent foot fatigue and injury.
