In reply to Hannes:

Are these still available in the UK? My last pair have started to lose their edge and I'd love to replace them as they've been my regular sport and trad shoe for the last 3 or 4 years but I can't seem to find them anywhere.
To the OP: Sportiva Miura VSs are the stiffest shoes I've used.
