Footie/Sock Bottoms: No Skid?

I just made some adorable footies for my youngest child, but she slips on the floor when she runs around. Does anyone know where to purchase “anti-skid” things to put on the bottom?

Thank you!

Check out the FT Clogs thread in the Knit Along forum. I think some people have tried squiggles of fabric paint on the bottom of the clogs to add some traction, and I think there is some specific product that shoemakers have like that as well, but I don’t recall what it’s called.

Thank you very much! I will check it out!

What an interesting product! It almost looks like the bottom of a ballet slipper!
