Those look nice, good price, and I like the mesh. They appear to not have full side zips, just most of the calf, which I think opens enough that you can pull them on and off without removing your shoes, you'll just get a little water and grit inside them. I don't yet have waterproof shoe covers, but I haven't toured in decades, though rainwear does matter for 3 hour rides local (I don't go out in the rain but sometimes get caught in it). I like the idea noted way above about nylon sandals if not too cold, those are also good around camp and walking if you are biking in stiff shoes (my mountain SPDs are still too stiff to comfortably walk in, but that is much better on the pedals).

I like carrying winter tights and some sort of shell pant for added warmth when cold, and rain pant when wet. If it's cold, the small amount of sweat is not a problem and microfleece pants wick well. If it's warm and wet, I usually wear rain pants over just nylon shorts or swim trunks. Even if not needed on the road, both fleece and shell pants are nice for lounging around in camp where you are not doing high exertion and may get cold. Hat, I either have a thin windstopper microfleece inside the helmet or a shower cap on the outside, or both if it is cold. The fleece pants and hat can also be an additional layer when sleeping, if I am carrying a lighter sleeping bag. A system.

I always wear glasses for object and UV protection, bright or dark, dry or wet.
