All the way up to the ankles, and all the way down to the tips of the toes.
@Snoogz, check the pockets. Is there a label in any of them? The corneliani for PRL pants and jacket I've found had similar labels, but yours just look like they're NWT. I think my pants had a tag in the back pocket or at the back of the waist under the waist hem (can't think of what else to call it!).
Well done man! I found a pair of their pants and I love them. Just had to have them lengthened slightly, but they're amazing!
Start with a suede eraser if you have any bad stains (e.g., dirt); you can find these anywhere. Then I use the Saphir suede cleaner, which is basically a shampoo. Let dry and the brush with a suede brush. Then treat with Saphir Renovateur suede spray, Saphir Super Invulner waterproofing spray, or just plain Terrago suede protector.
Bottom line you need a suede eraser, which you can pick up anywhere. I'm not familiar with the range of suede shampoos, but I've had good luck with Saphir. Then all you really need is Terrago, which you can find all over, to waterproof and protect against stains.
I have a pair of Peal suede chukka boots (crazy sale on them at the moment; warning, run narrow) with a Dainite sole and it's been my go to wet weather shoe. Combination of the rubber sole and the Terrago makes it perfect when there is rain out. (No, I'm not standing or running through puddles.)
I have a pair of gray flannels with the same tags. I figure if it's Corneliani, it's got to have the tag. Instead, like yours, it has the blue fabric/care tag on the pocket. Great question; would love to know the answer as well.
