Hmmm. I got a flat about 3 miles from civilization with no patch kit or cell phone. Come to think of it....no wallet either.

So I hoofed it back in my $60 Shimano mtb shoes w/ eggbeater cleats, and it was *not fun*. Given, those aren't the world's most comfy riding shoes, but 1) they were too stiff for concrete and 2) the cleats made contact with every step. Loose gravel / debris on pavement was the worst.
