Red marks from the Owlet Smart Sock are not a common occurrence. The small number of users who notice red marks on their baby’s foot after using the Smart Sock have found that the Sock was on too tight or they were using the wrong size fabric sock. The Smart Sock is similar to when a baby shoe is too tight or too small and leads to discomfort for the child or the potential for pressure marks. Our research, in partnership with dermatologists and pediatricians, shows that these rarely occurring marks are not burns.
