rubber: lacrosse alphaburly all the way. or irish setter exoflex.
dont wear any other kind. my lacrosse boots have stayed waterproof and toasty warm in the woods on the snowmobile trails and ice fishing hundreds of hours per winter on the frigid st lawrence river, for 4 years now. and i pound them. around the toes and top of the foot and heel are just plain black rubber now (the camo has nearly warn right off) and they are still 100%. they will last me several more years then ill buy another pair.
