In reply to Roger Irrelevant: Been using Evolv Defy as my main shoes for the last 3 years and they excel as a comfortable all round shoe.
They are less stiff than many other shoes but are superbly comfortable straight out the box and the rubber offers an excellent blend of stiffness, good friction and reasonable durability. I also can't fault the build quality of any of the pairs I've had.
For long days outdoors standing around and doing a few easy routes the Vantages are probably better but for indoor climbing and more technical sport climbing or bouldering the Defy are probably more suitable.
However, I do need to admit a vested interest as I supply Evolv shoes to some of the climbers and climbing clubs I work with.
