Or you should try not wearing shoes for level 30.
When crafters get to the point where they can reliably make things with buffalo leather (mid 20s) then those shoes will be easy to repair.
If you have so much play time that you are already rank / level 30, and you had time to shout "all day" looking for someone to repair, you have time to go level up the craft and harvesting skills necessary to repair your own shoes. You've out leveled the crafters you need to support your repair needs.
You can wait for the crafting economy to catch up to you or you can level up the crafts you need. You sprinted way ahead of the pack and now your complaining that it's lonely and there's no one to race against :-P
First of all, these shoes are from level 20 guildleve and they are rank 27, when I got them I was rank 18, now am 19.
Also the day after I got a rank 29 body gear from a level 20 quest, the item to repair it from weaver is level 20+, and repair cost is 54k.
The best thing to do is, drop the gear am using in my retainer and go buy level 19 gear, and by the way I leveled goldsmith to 12 to repair my rings, blacksmith to 13 to repair my sword and armor craft to 12 repair my shield, and now leveling leatherworking to repair my shoes, is that fun? (NO ITS NOT).
