What do you guys think of these? Do they help a lot with heel/toe or do they just get in the way?

 

I don't know about those ones specifically. I hated the thought of buying them but installed a set in one of my cars for bling factor at car shows but honestly...they help. If a car is set up for proper heel/toe driving from the factory they're totally unnecessary. They would be a hindrance in the Miata for example. It's completely possible to heel/toe an Accent without them but it is easier and more natural in the car with some modest pedal extensions. Mine mostly bumps out on the right side of the brake pedal.
