Makes sense to me, but then it doesn't get seriously cold here either. I have a pair of commute sandals (6-6-1) and lots of wool socks (DeFeet Woolie Boolie's are my favorite), so most of the time sandals make sense.

However, on super-cold days (i.e. anything under 40 Deg.F) and in rain (like yesterday and this morning) I have some Answer BMX shoes that work well (though they do take a long time to dry once soaked).

Both sandals and shoes are SPD compatible, so no worries there.
