i have two pairs of snow shoes all with broken straps. I was thinking some sort of rachet or bungee might work to strap them to your boot? Otherwise I wonder if a whole new assembly replacing where the straps were mounted is in order?
You can try but I really doubt it. Try a heavy-equipment shop, or a tire shop that serves farmers and loggers and whatnot; they might have a junk tube they'll let go of for a reasonable price. If you have "river inner tube" tours, like we do in the upper Midwest, maybe they'll let you dumpster-dive for junk tubes. The rubber on my bindings is probably 1/4" thick.https://www.harborfreight.com/mater...8-in-inner-tube-with-straight-stem-61240.html
would an inner tube this size be sufficient? I called Tractor Supply and they said they don't have tractor tire inner tubes!
