Have you tried? My Steve Madden clogs with the 4 1/2" platforms (heel only about 1" higher than the sole) are lighter than my tennies, and I'd happily run around the block in them. I don't know what the heck polymer the soles are made of, but I was insanely happy when I found a black pair at the thrift store several years back that were identical to the brown ones I bought in NYC in '97.

(My Nine West maryjanes, OTOH, are clunky as all hell. But they were too cute to pass up for $4 and obviously never worn.)

Assuming the issue isn't the wedge/platformness itself, of course. In which case, yeah, not much to find from either brand...
