Trad Climbing
You'll need a nice pair of flat, lace-up shoes to go with your hemp rope, rack of hexes, and old, beat up cams. And, because you'll be hauling all of that gear up the wall on painful foot jams, it's best to at least get yourself a comfortable pair of climbing shoes while you're at it. But here's the best part. Since you won't need to replace any of the rest of your gear for years or decades, you can splurge on the shoes, and get yourself that pair you've been eyeballing for the last two years.
