Calf-height and made for engineer boots. The BSX-1 is long enough to sit above the shaft of a tall boot, keeping the sock in place and visible. The main yarn is Dralon cotton, a high-bulk acrylic blend that manages moisture and holds pile structure well inside a closed boot.
Construction is specific where it counts: pile knitting at heel and ball of foot for cushioning underfoot, reinforced Achilles thread to resist friction from boot linings, mesh knitting through the leg for breathability. Curled yarn at toe and heel adds grip.
Wine shows well against natural leather or brown boots. A subtle colour choice that adds interest without being conspicuous.
