I have a child in the crawling stage and needed a solution for the cold season. We now always apply the padded Tinsulate toddler boots and above the Playshoes. Unfortunately, Playshoes at the seam are water-permeable. But that is so low that our child through the toddler boots worn underneath does not get wet feet on a wet lawn. The padding is thick enough for it. Value for 10 definitely be money. Regenfüßlinge with welded seams I have never discovered.
