7 Sports-Shoe Features for the Gym You Should Look For

2. Cushioning and Shock Absorption

Cushioning affects comfort and how your body handles impact. For long cardio or treadmill work, more cushioning reduces knee and hip stress. For lifting or platform work, too-soft cushioning can feel unstable when you need a firm base. Lab testing shows big differences: some foam blends score higher on energy return while others prioritize softness. For example, certain popular running-derived midsoles measure notably softer in durometer tests yet still return energy efficiently. When you try shoes, press the midsole with your thumb to sense firmness; a responsive midsole will compress then spring back quickly. Look for manufacturer specs or reviews that list stack height and foam type — these tell you how much material is between foot and floor. If your routine includes HIIT with jumps, aim for moderate cushioning with quick rebound. If your focus is heavy sets and compound lifts, prioritize denser foam in the heel and midfoot for a stable feel without unnecessary sink.
