How do I find out the model of my shifters?

I recently bought my first road bike, a Cannondale Caad8 which runs a Shimano Sora shifter/brake.

I want to replace the brake hoods, because they've done that thing where the rubber goes disgusting and sticky.

But, where can I find the exact model number so I can order new hoods?
when I pull the brakes there's no numbers hidden inside the lever, and even peeling back one of the hoods (from the lever pivot side) didn't reveal anything.

I've added pics in case anyone knows by sight, or can point out where to look.

Cheers!
