Annoying Noise with Every Step - Avoid This AIR ZOOM TR 1! Rating: 0/10 This product is incredibly frustrating. Every step you take produces an annoying sound, like cardboard being folded repeatedly. It’s not just an occasional issue; it happens with every single step. I can’t recommend this product at all due to the constant, irritating noise it makes. Save yourself the headache and avoid it. I tried using it in the mall. The sound was still there, and it felt like there was a constant clicking sensation inside because the material kept folding and unfolding. It’s incredibly annoying.
