OR Croc gaiters have their place (I own a pair) but they are way overkill for your situation. This is (or was) a lightweight site so I recommend that you get dirty:

I have used gaiters for many years and have learned to avoid the types that run anything under your shoe. Sooner or later it WILL wear out. Velcro on the heel types are lighter and simpler to use.

Caveat: There are exceptions to every rule, like the Crocs I use for mountaineering or snowshoeing.
