How much do the boot fittings weigh, and are they durable?
The Dynafit fittings molded into a Dynafit compatible boot weigh 1.1 oz (32g) per boot. They are installed during boot manufacture. The toe fitting is molded in, and the heel fitting is installed in a machined pocket and held by a screw and locator pin. The fittings (sans boot) are not available for retail sale, though they can be easily removed from worn out boots. The heel fitting is easy to remove (back out screw and pry the fitting out. To remove the toe fitting, grind the sole off below the toe fitting. Once the bottom of the toe fitting is exposed, pry it out. As to durability, there have been few reported problems. The heel fitting can loosen and become detached after heavy use. To prevent that, see this mod.
