I don't even use clipless and my 'bike' shoes are a dilapidated pair of running shoes, and I keep 'work' shoes at work full time in my locker. (They are also running shoes, but more presentable). I also keep jeans and towel at work, and bring them home for laundering occasionally. Daily I bring just a shirt, socks, and underwear. And in case I forget those, I even have emergency backup shirt and underwear at work.
