At first I didn't like the support under the pedal, but I found it is comfortable when I am wearing my uniform with my boots. Since my boots are thicker than regular shoes, they naturally rest on the support and it works out just fine. But when I'm wearing regular shoes, my heel naturally rests on the floormat so I don't even notice the support. Now I'm thinking my shoes are going to wear a hole in the floor mat, might be time for me to get some rubber mats. As for the gas here in England, off base is 98 octane and it is like 9 dollars a gallon, but I buy gas on base for 2.51 a gal. Although our gas on base is a little watered down, it is still 95 octane. So far the car likes it.
