Are trail runners a good idea even for snowy days? I have brooks cascadias and have never hiked in anything but a trail running shoe, however, Ive never done extended hikes through the snow wearing them. Im starting my thru hike on March 10th and know that there will be quite a bit of snow starting out. Should I get a waterproof hiking shoe/boot to wear through the rest of the cold weather or should I just stick to the trail runners?
