Excellent for my 1.5 and 3-year-old children. They don't slip on the tiles now during winter. I put them in the dryer and they didn't get damaged. Don't get a bigger size than what the child wears because their little foot will slip left/right, without any fear of twisting the foot. The silicone on the bottom is very soft! I was thrilled with these socks, especially for my older child, who runs and climbs everywhere and sometimes slips even with socks that have scattered "suction cups" on the bottom.
