Marty, I don't know where you paddle but I know that broken beer bottles are a sad reality on some of my paddling destination shores here in Moreton Bay
And further North on the Capricornia coast a coral cut on my feet would not be all that much fun.
Since I have seen several people cut their feet I thought the shoes would a good idea.
Do you have any other sensible suggestions to prevent cut feet?
OK I'll pay the broken beer bottle excuse, but as a cairns paddler potential coral cuts are no reason to dress like a Mexican.
As to prevention I find being a self employed web designer and therefore never wearing shoes builds up a nice amount of natural protection.
