A vamp is hand-knit from homespun wool and it’s basically the business end of a sock. It sort of ignores the leg part and you’ve got the full foot, the heel and, then it cuts off. A vamp is generally used in boots intended to be a oversized anyway, especially when you had handmade boots. The vamp then of course added warmth, there was some comfort in there to stop chafing, and I guess probably a cushioning factor too, in the bottom of the boot. You know you had many many families with their own sheep, so the whole process would come through probably in the one family. Therefore I think all of these things then have some special meaning, over and above going out somewhere to buy a pair of vamps.
