I need to select a pair of shoes for when I go out to Yosemite this weekend. The weather has been fluctuating like crazy - last we checked, there was a foot of snow on the ground, but now the lowlands are completely melted. I had originally planned on bringing my pair of cold weather boots, but it's looking like the weather might be in the range of 40-80F (4.4-26.7C) now. I have a pair of trail shoes I could bring, but I'm not certain if they're up to doing 20+ miles in 3 days. I could buy a new pair of hiking boots, but that's shelling out a little bit more money now.
Has anyone taken a pair of cold weather boots out in the spring before? Did you have any issues with them being too warm? Would you do it again, or would you rather use a separate pair of hiking boots?
