In reply to Dave Park:
If you local wall has a shop, then you can try before you buy.
I tried 2 shoes at the Manchester Climbing Centre, both on routes and bouldering. Quite like one, but have put that on hold whilst they order me another shoe in my size so I can try that one.
That's the sort of service you need to get the right boot for you.
I also have the Anazasi's which i use for bouldering and when i first bought them, they were tight. They still are now, nearly 2 years on, but they have given somewhat.
My toes are curled over and the knuckles come out flattened and hurting a little after a session bouldering.
But they are better for bouldering for it.
The new boots will be more of a flat foot for routes.
