These are probably the most comfortable shoe i've ever worn, and they do just about everything very well... The only reason I don't give them a "5" is because of the rubber... the Fusion 3 just doesn't measure up to Five Ten or even LaSportiva, but when there're re-soled with C4 these shoes are the bomb. They edge nicely and are phenominal in cracks. It is a board lasted shoe, so they're not as sensitive as some might like a climbing shoe to be, but they can be re-soled many more times than slip-lasted shoes, giving them more bang for your buck. I sized mine 1/2 size down from my street size, and they are nice and snug but not too tight.
