Looks extremely un-aero :)

Try the LA 84s mentioned by Gerlach for an aero option.

I prefer a shoe that fits properly. :) YMMV.

yes I have to agree. Awesome shoe for sure. The sizing is off, and even worse if you got them 2 or more years ago. They changed their size chart but if you measure your foot as they say you should, it is spot on. For example, I got a new pair 2 or 3 years ago and it had me at a 45.5 (I'm a 12US running shoe). I found these a tad bit too small so only rode them on the trainer for 4 or 5 hours max, hoping they would stretch. I liked them so much, despite the size issues, that I looked to get a new pair. When researching I found they changed their size chart. My 45.5s from a few years ago would probably fit an 11.5 perfectly, a 46 probably would have been a better fit for me. The newest sizing has me in a 47, and that fits perfectly. I am a 46 Giro, which also fits me perfectly.
All in all a great shoe.
