I guess it depends. Steet riding? Honestly, i have zero experience in track riding. I'm not interested in it at all, never done it. I've been riding fixed bikes since the late 90's though. I tried SPDs(after riding track pedals and clips/straps) and honestly, for riding all day, on the street, they were uncomfortable, to me. They felt like they were pushing into the balls of my feet through the shoes. After that, i switched to cheap BMX platforms, and toes clips/leather straps and never looked back. Also, riding on the street, i dont wanna be locked in, if i get t boned by a driver not giving me my left turn. Ive been hit, and rolled over the hood, Starskey and Hutch Style, and i cant imagine doing that, with a bike still attached to me. Might rip yer leg off.
I have to agree with this, and I've street ridden with SPD's and looks, I always come back to straps/cages.. and trust me I've had a few hairy situations with the SPD's that in the same scenario was no issue with straps/cages.
