We are often asked why some Ethernet cables have boots and some do not. What is the purpose of the boot and does the colour of the boot make any difference. Basically, on an Ethernet cable, some boots are molded and some are snagless. The snagless boot, as the name suggests, prevents the clip on the boot being snagged, caught or damaged. A molded boot does not offer this protection. The colour of the boot simply helps network engineers identify which cable comes from which device, the cable inside is wired exactly the same. The image below shows a snagless green boot.
