I've heard about driving shoes, but does anyone have them? I know sparco makes some.. I have been driving in my 4 year old adidas sneakers that have the soles worn paper thin so it's great for 6spd driving. When i drive in thick-soled shoes, it seems harder to drive / shift as precisely (less pedal feel?). Would driving shoes be the thing for this? Mainly i'm trying to find something with a thin sole and comfortable / flexible.
