In reply to P Baillie:
All the big brands stopped making them years ago, so the only shoes available tend to be in tiny sizes, which is fine if you are a small woman. Joe Brown still sell La sportiva Rock Jocks
If you are a bloke then GoOutdoors still sell the Mad Rock Frenzy EZ in bigger sizes, but you can only get them instore.
e-bay is your best bet, but this can be a lottery: got myself a brand new pair of Rock Jocks but they turned out too small. I would be more than happy to sell these, only used a couple of times, size 9 1/2! Having done a search on here, opinions were very positive.
Other models to look out for are Scarpa Marathon, Red Chili Tornado, 5.10 V Mile, and another 5.10 model which predates it, but I cannot remember the name
