Non-Slip Shoe Pads, Self-Adhesive Anti-Slip Sole Sticker Protector, Premium Odorless Silicone Non Skid Shoe Grips for High Heels (4 Black + 4 Beige)

Q: Can they be used by children? How is the effect?

The non-slip shoe pads was easy to trim these to the exact size and shape I needed, they adhere firmly, are thin enough that I don't notice any difference in the weight of the sandals, and they don't slip at all.

Q: what do you clean tennis shoe bottoms with to make sure they stick, alcohol?

I just used an old sponge with some water and a bit of dawn … you can use any cleaner I think….. and rinse off….! They work well !

Q: Will these leave terrible black marks on the floor?

Not at all. These shoe pads are made of odorless silicone, which is more wear-resistant than the rubber material I bought before. There is no other smell. Recommend.
