I have a pair of the original Peregrines that I picked up on clearance. Like Hartley says, the uppers are flimsy (but I like that they dry insanely fast and stretch quite a bit so the toe box doesn't feel *too* confining). I've been wearing mine for trail runs and weekend backpacking trips since early March, and the tread is hardly showing wear after a couple hundred miles. It is also quite sticky and has done pretty well on both wet and dry rock.
Tried on some Peregrine 2's to see if it would be worth sticking with the brand. The fit, as with the original model, is quite true to size. I wear a women's 9 in these, versus a 9.5 in Inov-8, Montrail, etc. If you can find them on sale, they're an okay deal but don't expect to get more than a season out of them. I decided not to get another pair because I really need something with a wider toebox.
