Make your own is the quickest fix. When I ran trap lines many years ago I made my own snowshoes from scratch... not all that hard. Depending on what the bindings are if metal and you still have them will determine what will work best with them. But you don't need them to get the shoes back in use. Have a bunch of 550 paracord that would work in a pinch, nylon straps from tent and awning, camping equipment or military surplus stores would also work just fine. Oherwise from the original MFG or supplier, a north woods catalog store, trapping supply house, etc is a starting place.
