Probably the best shoe on the market along with its lace up counterpart. The c4 rubber cannot be beaten for stickyness. I have worn many different shoes, scarpa, boreal, madrock etc, but for the past 3 years nothing can depart me from the velcro anasazis. They are superb for smearing and delicate edging. HIGHLY reccommended.
The only flaw I can find with them is that the heel is not quite as good for delicate hooking on small edges as the lace up connterparts, but is still better than most of the competitors. Velcro allows them to be taken off easily after each attempt on a boulder problem. If you are doing mostly roultes I would probably go for the lase up version.
