Sparco slip on rubber overshoes. Part number 002431.
These solve a small problem properly. Race boots have thin soles so you can feel the pedals, and thin soles are ruined by walking across a gravel paddock, standing in a wet pit lane or scuffing round the garage. Overshoes go over the boots for everything that is not driving, and come off at the car.
A pair of race boots is not cheap and it is a consumable if you walk about in them. These make a set last considerably longer.
The other use
Keeping oil, fuel and mud off the pedals. If you have been under the car and then get in it, whatever is on your soles goes onto the pedal faces. Overshoes stop that, and a brake pedal with oil on it is a genuinely dangerous thing.
Sizes
S at UK 3.5, M at UK 5.5, L at UK 7 and XL at UK 10.5, in neoprene.
Size them to go over your boots rather than to your foot. If you are between sizes, take the larger, because a tight overshoe is a nuisance to get on and off and you will stop bothering with it.
