Yes, those are side-zips. I think they could look pretty cool with loose grey trousers and the like. IIRC, your wardrobe is perhaps not that friendly to the color, though? And depending on the stiffness of that shaft, which is variable between leather treatments, they are probably not that malleable. Slim jeans (P'tit s) aren't likely to fit over the boot opening, is it's just a wide shaft (no zip) but it's possible with smaller sized shoe. I think it's a toss up, but it could be awesome. I would love a pair in the cream suede.
