They are "poo-pooed" because the claims made for them are absolutely ludicrous, and at the end of the day the only thing they make you better at are riding powercranks. They're just an absolute gimmick and completely pointless. Only good thing about them was that I was able to sell mine for $!50 more than I bought them!
But as with everything, what's old is now new.

You're probably right. I can feel my heelcups and shoe uppers on the upstroke, but that's not lifting the weight of a powercrank, just my leg. I don't think I'd do better if I lifted any harder - or I would. The weird thing to me is that they still ebay for $300-$700. Lot of money for worthless junk . . .I'd try a set for $100.
But you did OK on them eventually? Except that they didn't improve your power or endurance?
What's that scantron? It doesn't google. My wife has a computtrainer, older model, but no electronics attached other than its head unit. I always wanted to see a polar graph of my pedaling.
Have a look at this, 2:06-2:13. I've been fascinated by the identical pedaling of these riders. They both lift the toe on the backstroke. I've tried and tried to do that at high power, and I just can't for more than a few strokes, though it's obviously better to enter the power stroke early, 11:00, with the toe well up. Comment please?
Yeah, that kind of thing engages the core alright.
