Non-slip performance is a core requirement for kids’ slippers. Currently, there is no unified global standard, but their anti-slip ability can be determined by key indicators.
Prioritize checking the sole structure. Qualified products must have deep, dense grooves to enhance friction on smooth or wet surfaces. Avoid flat-soled or shallow-groove styles, as they lack sufficient grip.
Sole material affects anti-slip effectiveness. Rubber and high-quality EVA materials are superior to soft, thin fabric soles. It is recommended to choose styles marked "non-slip" with a slightly rough texture and good flexibility—overly hard soles reduce adaptability to different floor surfaces.
Although there is no unified standard, regular manufacturers conduct friction tests on both dry and wet floors to ensure the soles provide adequate grip in both scenarios and guarantee safe use.
