In comments under the Space SE question Why do EVA suits have legs? the OP clarifies that for a humanoid astronaut performing extravehicular activities their suit may not need individual legs but instead there could be a single "leg" or a hard shell or pod.

This brings (vaguely) to mind some old SciFi cover art with humanoid astronauts wearing exactly this; a hard shell or "pod" lower half and more of a "suit" like upper half with legs, either doing work or jetting a short distance from one object to the next as part of some activity.

Is this enough of a description to track this down?

This is the type of suit described in "Islands in the Sky", a novel by Arthur C. Clarke. Published in 1952, I guess this counts as "vintage" sci-fi. Similarly to the remarks given in the question, Clarke wrote:

To most people, the word "space suit" conjures up a picture of something like a diving dress, in which a man can walk and use his arms. Such suits are, of course, used on places like the moon. But on a space station, where there's no gravity, your legs aren't much use anyway, because outside you have to blow yourself round with tiny rocket units.

and so the people on the space station used a design which did not have legs:

For this reason, the lower part of the suit was simply a rigid cylinder. When I climbed inside it, I found that I could use my feet only to work some control pedals, which I was careful not to touch. There was a little seat, and a transparent dome covering the top of the cylinder gave me good visibility. I could use my hands and arms.

The cover art shows the features clearly.
