There is one seam across the front of the toes, but it is surprisingly soft as well. No seam at the heal area, though. Like most men's socks, they fit a wide range of feet with one size, so I find them roomy enough that the front ends are not pulled tight against my toes.

As far as sheets, there is a "new" (to me, anyway) type that are made of bamboo fibers. My daughter got two sets for wedding gifts and she claims they are very comfortable. I have not tried them, but it is very chic right now. I believe they are somewhat pricy, so I wouldn't suggest buying them unless you try them somewhere or get other recommendations. Has anyone tried the bamboo sheets?

I saw some bamboo T shirts at a little shop on the coast - they were very soft. I was surprised at that.
