I've had mine for probably 2 years now and never had them drag.  If you're a peg dragger, they'll hit first.  If you ride like most people, you shouldn't have a problem.

They are a little on the tight side around your feet.  I have to slide my foot back and then under or over the gear shift. There's not enough room to just slide it to the side.

I wear 9.5 wide. It's not a big deal sliding my foot like that. It just took a little getting in practice.  I don't even think about it now.

The quality is good.  The chrome seems to be nice and thick.  They are not rusting or anything. The welds are good beads all around. They are made of good strong materials.

You can rest the backs of your ankles on them.  The top is actually closer to you.  Can't get your feet on the bottom due to the pegs just above the bottom. Some pegs on the outside ends of them may give you just a little more distance. I see no way to use them with extended controls. You'd have to put your feet through them. They do vibrate quite well at certain rpms.  Nothing bad but you can feel it if your feet are on them.

I'm 6'1" with a 33" inseam.  Most bikes feel all crunched up to me since they stopped making big enough frames somewhere in the 70's or early 80's.  You should see me fold up on the little ninja 250.  I like something nice and spread out like my old goldwing.  I have drug the valve covers on it a couple times.
