The 3pk. Non-Skid Shoe Socks I purchased for my grand daughter are the sweetest little shoe socks I've ever bought for her. Not only do they finish off an outfit, (the frosting on the cake), but the grippers at the bottom really grip the floor as she jumps up and down in her bouncy activity center, and the more she bounces, the happier she is. So these adorable Non-Skid Shoe Socks make my day and hers a much happier one!
