>>2686361trail runners are better than boots in deep mud, there is no debate on that. I've drudged through bogs in these trail runners, boots and rubber wellingtons
Wellingtons - Completely dry but heavy and most energy expended as the suction effect is most pronounced, feet are drenched anyway with sweat
boots - doesn't matter how careful you are, you are going to get wet, boots fill up with water and now you just have cold, wet feet and boots that takes ages to dry
Trail runners - essentially just plimsoles with soft luggged rubber spikes on the bottom, dont absorb much water, a delight to use and the most confident grip
