In reply to jon:
In a word, yes! I got some on eBay about a month ago, they had no signs of use, so pretty much brand new (£40!).
First try, agony, especially on the toe knuckles. I thought they would be going back on to sell. But I persisted, wore them sitting around, even used socks to help with the stretch and reduce the pain. Took them out sport climbing and a bit of bouldering past couple of weeks. First day was a bit painful, but now they've found the shape of my foot, and I daresay they are comfy.
Performance wise, they are probably way above my skill level, like putting Mrs. Doyle in a Ferrari. But hey £40, new shoes.
For reference I'm a size 44 street shoe and they are 43s. LS sizing guide says you should downsize 2 euro sizes, but I can't see myself ever doing that.
