Sterile boot covers are made of comfortable fabric and include non-skid soles to help prevent accidental slips as you work. Boot covers provide protection from liquids and particulates, so your shoes stay pristine. Each boot cover is low-linting and sterilized to a 10?6 sterility assurance level (SAL). The fabric helps reduce the release of unwanted particulates in your work area while tunnelized elastic provides a more secure fit. This also eliminates raw edges that may generate unwanted particulates. Each pair of boot covers is individually packaged to help prevent cross-contamination.
