In addition it's 360º reflective, non-metallic and has built in EN/UKCA certified Metatarsal Protection (M) and supper strong pull levers for fitting support.Cold Insulation (CI) and Heat Insulation (HI) certification ensures all-day comfort.BBZ9000 features a super lightweight nano safety toecap, a lightweight anti-penetration midsole and a weight saving sole bonding process. It's comparable in weight to its moulded polyurethane competitors and just like its older brother it fits like a glove, not like a tube.BBZ9000 is a great product from the ground up so it is vital that the soles incorporate the very latest tread design techniques to maximise grip, extend life and reduce weight. The new BBZ S5 rubber outsole does all of these plus it comes with SR maximum anti-slip certification and is non-marking whilst now offer ladder grip support.
