In reply to Dai Horribly:
Both are probably good for the purpose, but with approach shoes it's essential to try them on. They tend to be narrower in the forefoot than running shoes, for the sake of climbing performance, and the Gandas being some of the most climbing oriented approach shoes on the market are a particularly extreme example. They're probably great if they fit you; I can barely get my feet into them without going at least a full Euro size too long.
