Personally, I ride between buildings on campus to get to various meetings. All within about a 2-mile area, and I don't have time to keep swapping shoes (why would I want to for short rides anyway?).

My bike came with metal platform pedals that have little buds (~1/8 " tall and spread all over both sides). They grip my shoes well and I haven't had any issues, even in the rain. Something akin to this:

These in particular are Wellgos and $12...

I do it because roads here nasty!

I have it on good authority that these pedals work well with Prada pumps, and other "kick-ass heels", should you have any. :lol:

UPDATE:

Got my RMX pedals, and they seem to work great! Comfy, nice and wide, and my shoe doesn't slip off easily. They look pretty cool too!

Agreed - if you're riding for any great distance, it's probably worth carrying the extra pair of shoes. Or, as an alternative, either leave your dress shoes at work or take the money you WOULD have spent on new pedals and buy a new pair of dress shoes to leave at the office :) I have a complete second set of toiletries, extra shirts, pants, shoes etc that I leave at work in case I either a) forget something, or b) don't want to carry as much.

Good reason :)
