So asides from that: How do I keep my hands and feet from getting torn up on concrete/brick/ROCKS?
Also: Should I just practice running barefoot?
#1: Build calluses. Unless you really go crazy on stuff, your hands won't get TORN UP as you think they will. However, wall
climbing can take a toll on your hands, but training on your own pace will be enough to let them toughen up.
#2: Go run. Try with shoes, then try without. Tell yourself which one feels better. First time I did that, I run a mile with
shoes, then ran back home without. I almost fell from how fast I could go without them.
After you get used your foot movement, running with padded shoes should become easier, faster, and more efficient.
