They are very thick, soft and of good quality. I love that they have a texture that is sure to help little feet crawl and have a good grip. I have only one problem. I bought what was labeled "14mm" although the pictures say it was "15mm" and the package I received says 10mm and of course 10mm. Update, the company contacted me directly and offered to fix the issue. They were very responsive and that completely makes up for the error.
