Socks are more of a one size fits all approach. Had them, didn't like them. I have a smallish foot (US 9) and the sock was just too bulky. There is no size of sock, you just get it. I tried 2 different rock boots, shoes, and the worst was a wetsuit booty. The booty I went to the dive shop, put the suit on and tried several boots until I found one that felt like a pretty good fit. In the water the fin stayed on the boot, the boot stayed in the sock, and my foot was working itself out of the sock. That turned into a quick shallow dive, tried a few more times that day to fine tune stuff, gave the boots away.
I also tried a suit with oversized attached boots and that sucked as my feet just flopped around inside the boots.
The last suit I ordered up with properly sized attached tech boots. Velcro wrap at the ankle. This works perfect (for me). The first time I have been happy with my feet in a drysuit. I also keep the fin size down to a normal size. With the half dozen layers of rock boots or wetsuit boots I was having to use fins with larger fin pockets so my feet would go into them and not just my toes. Yes, this was a long steep and expensive learning curve for me. As of the past couple of years it has leveled off into a working system.
I also hated lacing boots/shoes. hard to do wearing a drysuit. Laces either kept coming undone or would not come undone at the end of the dive. The shop's owner will only do socks and boots.
I try to minimize the shore hikes and do mostly boat dives. I've heard that socks and rock boots are a better choice if you like to do a death march while fully geared up. I try to keep the hikes as short as possible. This is dive gear, not hiking gear. But I understand some sites are a hike to get to.
But I am really a fan of a good set of attached boots that are properly sized.
Almost forgot about the drying of the suit. hang from the boots (wader hanger) or a couple of PVC pipes and a computer fan to push a light breeze through works just fine. No need to invert all the way tot he toes. You can still invert all the way to the ankle if need be.
