.....but leading, down climbing, then leading again or leading all three, pulling the ropes between each lead would be even better training!
Semantics aside, as much as people say "shoes don't make a difference until X grade" having a pair of shoes that I trust makes a massive difference. The key to climbing well is being able to use your feet and it's a lot easier if, when you put your toe onto that tiny edge or smear, your brains says, "that feels solid". I swear by Anasazi Velcros. Great all round shoe, edges well, smears well, pretty comfy. Having said that, I climbing indoors in instinct slippers as they have a little more power in the toe for steep stuff, i got them cheap and you don't get small footholds indoors so I don't need the velcro "magic", just the ability to toe-down.
X depends on the grade people climb, usually one grade below their onsight limit to allow them to buy new shoes but criticise others
