Yep, that's it alright. Though as toad_hall notes, it's rather pricey. $45 or so for a pair of socks is way too high for me. Now going in the other direction? Getting PAID $45 for knitting some socks? My mom could totally handle that. :)

Btw, Armstulpen are sort of like legwarmers for your arms-- gauntets with little holes for your thumb. Kind of odd, but probably helpful in cold areas.
