There's lots of differences! Some are for summer others for winter. Some are compression type others are not. Some have waterproofing some do not. There are lots of different gripper types and materials used. U need to decide what season/conditions you need them for and then do a bit of research to get the right ones for you. If you only want them for the chillier spring/autumn season then you'd be buying a different product to ones you want for winterSome have fleecy linings some don't. Other than that no real difference
