Yep. I played soccer from the time I was six through college, did lots of orienteering and spelunking and that was before going into the Army. One can never underestimate the value of healthy feet. No matter how heavy a ruck I would hump, there was always room for one more ziplock sandwich bag with a pair of clean dry socks; worth their weight in gold. I still do a lot of recreational backpacking/camping, though now I have to pay for the equipment.
Where do we turn in our old worn-out husks for new models?
