Favotite cheap socks with rubber grippers for learning to walk?

AB

Baby boy is 7 months. Crawls well, pulls up and is starting to cruise. It’s fall now and our floors can get chilly so we like to keep him in socks. Calf length would be a plus too.

Need recommendations for good socks off amazon with with rubber grips.

Baby boy is 99percentile so we are into 18month clothes/socks already.

Thanks!!!
