In rare cases, shoes may produce a squeaking sound while walking. This is usually caused by friction between the outsole and the floor surface — especially on smooth or special flooring such as vinyl, tiles, or damp surfaces.
This noise is completely harmless and not a quality defect. It often disappears on its own once the shoes are worn in or the sole becomes less smooth through regular use.
Tips to reduce squeaking:
Make sure the soles are dry — moisture can increase the effect.
Clean the outsoles regularly to remove dust or residue, which helps reduce friction.
