I've got some rubber boots for chores like that.  If they get dirty, I just hose them off and move on.  Nothing damages them.  I've had them for 8 years and they are as good as new.  I guess the only issue is if it is really hot, my feet get sweaty.  Since I'm not in a hot climate, that is only really an issue 3 months out of the year.  They handle, mud, snow, brambles, weed eaters (put my boots between bushes and weed eaters to get closer with girdling the bush/tree), and just about anything else. 

 Yes rubber boots are great too, and i use those when its rainy.  But its true, they get pretty hot.
