Finding a non-slip, right length sock is indeed a challenge! Just FYI, jabbers: I have found that Nordie's black housebrand athletic shorties stay put, and Smartwool makes several varieties of footies and no-shows that are perfect for our damp winters. And while you're breaking those gorgeous new booties in, remember Angie's advice about anti-friction gel: I can't get the product she recommends locally, but Walgreens carries a good one, Gold Bond Friction Ease (which our local store shelves with the, ahem, personal lubricants!)
My apologies if this is a hijack, CJ!
