Hi there, thank you for taking the time to leave a review for our Non-Slip Stay on Baby and Toddler Socks in Grey & White Stripe. We are so happy to hear that you are pleased with the quality and that the socks stay on your little one's feet. We understand that little ones can be quite active and may occasionally pull them off, but we're glad to hear they haven't left any marks on their legs. Thank you for your support and we hope you continue to enjoy our socks!
