New Blundstone #181 Work & Safety in Waxy Rustic Black meets most company uniform colour standards, even if the standard is blue jeans. The waxy finish protects the leather, packing more days into each boot. The patented Blundstone SPS (Shock Protection System) disperses shock at heel strike and reduces skeletal stress absorbing up to 90% of the impact as you walk. Seams over the instep, a key source of irritation, are avoided along with many potentially leaky stitch holes. Lightweight, one-finger easy, all-day comfort. Oh, we could wax on!
