"The Iron Mountain Workwear Premium 12 pair pack of men's workwear socks have been designed specifically for use whilst working in steel toe cap safety footwear to keep your feet comfortable and warm whilst on the job. They’ve been constructed with reinforced heel and toe sections to help make wearing safety shoes & boots more comfortable by providing added protection against the safety toe cap and heel areas in work boots which can cause foot discomfort. The cushioned and true heel and toe design prevent unnecessary and irritating movement whilst being worn and improves the fit and feel of the socks helping reduce irritation & itchy feet. The smooth toe seam has been designed to provide extra support against all steel toe cap or composite non-metallic work safety boots, shoes and trainers available. We’ve also added a Full foot length soft Terry Cushioning section which will absorb sweat and makes the socks feel super soft & ultra-comfortable for extended all day wear. These socks are manufactured using our in-house Therrn-Tech breathable fibre technology which utilises an innovate reinforced open loop fibre design which traps heat within the fibres and makes the socks supremely warm for those cold days on site whilst allowing sweat to be passed away from the foot. The fibres are constructed using recycled yarns originally sourced from sustainable sources. They are machine washable and are made from 80% cotton, 17% polyester, 3% elastane. Each 12 pair pack comes with 6 pairs with yellow contrast & 6 pairs with red contrast design. "
