Each metal-free shoe or boot is built using lightweight, protective composite toe caps and midsoles made of synthetic materials such as Kevlar, Carbon Fibres, Ballistic Nylon and other patented technologies. (Kevlar is used to stop bullets in ballistic vests - so having it as your underfoot midsole is very reassuring!)

These materials, (often referred as Composite toe caps), are as strong as the steel toe caps used typically in safety shoes and boots. Of course, they are ALL required to pass the same EU safety regulations (EN ISO 20345)as the steel options.
