baitWhat is the point of a bosster strap? what benefits does it have vs just using buckles?
It eliminates the dead spot in your boots that you get when you unweight or stand straight up. A normal non elastic strap you can only ream on so much before you cut off circulation, and because it is static when you flex into the tongue of your boot and then lean back or unweight your shins you'll create a small gap (aka deadspot) where there is no contact of the boot tongue against your shin. This dead spot can cause the dreaded shin bang since you are essentially freefalling an inch (or however big your deadspot is) straight onto a stiff flex boot tongue every time you weight and unweight.
Contrary to popular belief it doesn't actually make your boot stiffer, although it may give you the illusion that it is stiffer because the cuff will be properly suctioned to your shin at all times, therefore engaging the flex sooner than you would otherwise. I dunno, I guess maybe that counts as making it stiffer, you decide.
