We all know that SPD shoes can be worn off the bike (that is why they were designed), however there are not many SPD shoes that you would want to wear off-bike. There are even fewer (if any) SPD shoes that look presentable in a smart workplace. As for getting into one of those nightclubs with a strict 'your name's not down' door policy, as things stand, no SPD shoe would get you past the bouncers.
If you do know of any SPD shoes that look like normal 'interview grade' work-shoes please tell.
If you have looked for such a shoe and not found anything remotely appropriate, what would be in your dream specification? A gore-tex liner? Reflective heel tab? Carbon-fibre reinforced toe-box?
I am also interested in SPD shoes that you can and do wear to work and at work, particularly if they look completely different to the 'Shimano Golfing Shoe'(TM) / 'Bling innit' efforts foisted on the cycling public.
I know some people do not see any point whatsoever in a SPD shoe that you can wear all day or as part of a mixed transportation journey (e.g. cycle to the train station, catch the train and/or tube...) - it is different strokes/different folks. Some of us want to ride like the Dutch do - everywhere and all the time - but with some decent SPD pedals and sensible footwear.
