As many reviewers have stated, they are comfortable right out of the box, and true to size.  With regard to arch support, I have fallen arches and always replace the one in the shoe with Form Insoles, which are slightly stiff, but provide much needed support for my feet.  These beauties don't look like hiking shoes at all, and I use them primarily for travel, so the waterproof element is a great bonus (although Ive yet to be caught in a downpour). If i were an avid hiker, Id probably go for something with more support. I chose the black with green trim to match my green parka, and am thankful that Amazon has such a wide selection of colors to choose from!
