I just tried the sock on again and walked around on the (uncarpeted) kitchen floor, so I could answer your question. I can't feel the holes at all, and I can tell you I'm very sensitive to seams in socks. Although granted my toes are likely more sensitive than my heels. I think if you choose a soft squishy wool, you won't feel the holes. BUT what you could do as a test is knit one hexagon, put it on the floor, and stand on it.
