UPDATE 05/04/21 I decided to use them again when it came time to increase the size about a year later. My daughter is now a shoe size between 7-8 and 3t/5t which fits her perfectly and doesn't put pressure on her still thick calves. I bought them in rainbow colors and the colors are beautiful. We have new laminate floors and they help her not to slip. I'm still happy with the quality. Doesn't roll, and although the color will fade over time, the grip won't go away. I still recommend and wish my size 3yr 6yr had a pair too. End of update: Original post: covers WORK. I LOVE that they go from toe to arch so this really helped my 7 month old find her footing. My daughter has chubby calves so I was nervous because they marked her legs when they weren't. She wears size 3 so I ordered 12-36m and I'm glad I did. They wash well so I know they will last a while while she learns to walk. Just DO NOT wash with dark clothes. I made a mistake and the pair was washed with my clothes and the handles were dirty.
