What does improper footwear most directly increase the risk of during workouts?

Improper footwear most directly increases the risk of injury during workouts because shoes that do not provide adequate support, cushioning, or fit can lead to a variety of alignment issues and impact-related injuries. When athletes wear shoes that are worn out, the wrong size, or not suited for their specific activity, they are more susceptible to stresses on their feet, ankles, knees, and even hips. This can manifest as sprains, strains, blisters, or conditions like plantar fasciitis, which can significantly hinder performance and increase the likelihood of injury.

The other options are less directly connected to footwear. For instance, dehydration is primarily influenced by hydration practices rather than footwear. Muscle fatigue relates more to the intensity and duration of exercise rather than shoe choice. Cardiorespiratory issues are typically associated with fitness levels and exercise intensity, not the type of footwear. Therefore, the correct answer emphasizes the critical role that proper footwear plays in injury prevention during physical activity.
