In reply to UKC Gear:
Just started using the Instinct lace after throwing a very used pair of Anasazi Verde's away.
They've taken a bit of time to wear in. Initially thought I was going to have to cut my losses and get a different pair as they were agonising for the first couple of weeks. They seemed to provide little grip on the toe and the stiff sole hindered feedback, especially given the worn pair I'd just thrown.
Thery're starting to evolve and grip more, either that or my feet have changed shape but I do think it's improving my climbing. Still not sure whether I should have gone 1/2 a size larger but hope they'll continue to fit.
Just for reference, street shoe 10.5-11, Verde 10.5, Instinct 10.
