So, I have already bought a pair of trail runners for my upcoming thru attempt and no they are not gortex. I was watching some videos and saw the trail where it was nothing but icy slush. Everyone seems to recommend trail runners but what do you do in this situation? It seems like these conditions would be miserable in trail runners and possibly dangerous? Is hypothermia a concern? I know that it has been a mild winter, but I am not confident that it is over. Any advice would be appreciated! Would seal skins be a good solution?
