The solewear tends to be on the outer edges if there is pedal rub that can happen. As for flop around, if you put a little of your foot in and twist, it will have room for that. If you shove it far in and than twist to lock in, almost no flops. In fact, you can get it so tight it is uncomfortable (not the point I think).
There is that twisting locking motion the people who haven't used it often doesn't realize... (which is what probably was killing my sole on outer side... as I am locking... I was grinding my edges of shoe soles I bet)

I don't use them for commuting but all of my MTBs are equipped with them.

I'm in the smaller group of people that isn't a fan of them. I bought them to use with all the shoes I use to ride with - well turns out my shoes vary so much in size that I was stuck wearing one pair of shoes to ride in. I already had clipless shoes and pedals, just can never get them adjusted to not cause outrageous knee pain.

Now I don't run either, and I can wear any shoes I want. Will be trading my power grips off to my roomie, who loves them.

Yup, that is one thing I was wanting... being able to change length of grip on Powergrip on fly would be nice.

I like PowerGrips because I don't have to have special shoes to ride with.

Having used clipless, toe clips and platforms; I now have PowerGrips on all my bikes and won't use anything else for the kind of utility riding that I do.

I wonder if they could be cut a few inches too long for your largest shoe, and then sewn in with industrial strength velcro to make them adjustable.

Or why not just replace the Power Grips straps with two velcro strap pigtails (male and female)? Of course then you might as well just get a couple bolts w/ nylock nuts at the hardware store and do the whole thing yourself for $3-4.

the foot should not be moving around inside the Power Grips.

the way they are designed, your foot slides in at a slight inward angle. when your foot naturally straightens out, they tighten around your foot. extremely comfortable and great bang for the buck, can be used with your favorite shoe. if your shoe has a slight tread on the bottom this will "lock" your feet in place.

and when you get out, you slide out easily since you're not actually attached to the pedal.

i've never had Power Grips wear out my shoes, but your experience might be different. and i did ride at least 5,000 miles/year.

Which pedals should I use with my Power Grips?

You can trim off tre erxxcerss of the PG strap just like yoy can trim off the excess of a toestrap (nylon or leather).

I know how they work. I own PowerGrips. I used them for about a year before I switched to clipless. Read the OP's comments again. He specifically stated that he thinks because you can lift your foot slightly off of the pedal your pedal stroke will be more efficient due to less downward pressure on the upstroke. To lift your foot from the pedal the straps would have to be set a bit loose. It's that part I find to be silly. In no way would that be more efficient. It's not difficult to reduce downwards pressure on the upstroke with clipless. It takes practice to smooth out your pedal stroke.

The thing with PowerGrips is that to fit them snugly enough to be nearly as efficient as clipless pedals you're going to be limiting the circulation in your foot. I didn't adjust my straps tightly enough to completely eliminate play as it was uncomfortable. Even at that point, you're still not able to apply force forwards and rearwards (pedaling in a complete circle) in the same way as with clipless pedals.

I agree that they're great for being able to ride in casual shoes. My riding is either for leisure or for riding to work. In the case of the latter I'd be changing into my work shoes anyway so clipless is the best option for all of my riding.
