In reply to craig1983:
I think the problem with thestraps breaking is folk try and pull them over the foot to tighten them, rather than pulling the tab
outwards and away from the foot first, then bring the tab and strap back over to close the thing off. I've had mine for over a year now and they've had lots of use - the straps are both still fine (kiss of death saying that now, I realise!)
Have you tried the Miura VS, rather than the lace ups? I have both and for bouldering the VS are great, but still second to the Solutions. It's still the Miura lace-ups for routes however.
