I bought the Specialized MTB clipless recently - I have high arches also - as in Hang 10 feet!...I find them very comfortable for both riding and the occassions when I have to walk in them - as in walking the bike to her home or her parking spot @ work. They have the Velcro fasteners which makes it very easy on my arches as I can fasten the shoe to fit the arch. They are clipless tho and I know you said you weren't going clipless yet to which I say - why wait? I waited 6 wks and that was just 6 wks too long! I LOVE THEM!! No matter what tho - everyone is right...they have to be comfortable and fit you well!...Good Luck
Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, champagne in one hand, strawberries in the other, body thoroughly used up, totally worn out and screaming: "Yeah Baby! What a Ride!"
