In reply to nastyned:
Pretty much anything! They're not famed for being 'aggressive'- they're basically a flat shoe. At the moment, my go-to trad shoe is the laced Scarpa Techno X, which I would definitely recommend and seems in some ways a similar profile to the Spirit. It's a "technical flat shoe" design; it's pretty comfy, fairly stiff and tensioned around the heel without being an achilles killer. If fitted snugly, it feels very slightly downturned and edges very well. The toe design also seems good for jamming in cracks.
I feel complete trust in them - they fit well, stick well, and edge well. Also, Scarpa shoes seem well-made to me - certainly far more durable than La Sportiva in my experience. I also managed to get a pair of 5.10 Stoneland 'tech' laced shoes, for sub-£40 from Rock and Run. They're quite soft and flexible, but I've found I can stand on very small grit foot-hold "suggestions" (e.g. that starting hold that you have to look at in profile to even see). Super comfy and sticky, but certainly not "aggressive". The shoe is lined and feels a little bit luxurious! Still prefer the Techno, though!
p.s. check Ebay - sometimes you can pick up basically new shoes for £30.
