In reply to guyaustin:
I'd second what others have said about washing them - it seems to work for mine. If you have not worn them for ages they might be dusty?
Also initially I found that 5.10s are not that sticky (not as sticky as my Scarpas were) but it takes a while to get worn in.
Someone told me they initially have some kind of coating on that gets worn off. Not sure if that is correct though.
