You aren't looking for absolute brake traction, you just need to know if the road is still greased up or not. There is a hell of a big difference and I'd question if you couldn't tell, regardless of footwear. I can tell the difference from my work boots, to my street boots, to my track boots etc etc. Where this comes in REALLY handy is when you come out for work and everything is wet, well OK, did it just sprinkle and everything is slick as snot, or did I sleep through a gully-washer and the roads are fine. I used to, 45 miles one way. Really, the spring windy season was actually worse (I had to go over the Organ Mountains to get to work) 70mph "downsloped" winds for 5-6 miles makes for a lively commute. Plus you could usually see a monsoon storm coming in the form of flying dirt...like 20 miles in advance. Unless they are worse further north?
