invisible black dot anti-wear sole anti-slip mat (small, second generation)

Most anti-skid patterns on shoes are ineffective at preventing slipping, and it's still worrying to slip when walking on smooth tile surfaces! Self-adhesive anti-slip stickers are very convenient to use; just peel off the backing paper and stick it on the bottom of your shoes.
Attention: Please apply the anti-slip stickers to the areas where your feet touch the ground to maintain balance, starting from the center of the sole, not from the front edge.
Material: Natural rubber. After applying, there is no sensation of foreign objects when wearing shoes.
