Safety Jogger describes the original Modulo as metal free, with a puncture-resistant lightweight midsole, a scuff cap, ESD, a breathable upper and a BASF PU outsole, made from vegan materials. The S in S3S marks the non-metallic midsole. The editions change the upper and the fastening: TLS is Safety Jogger's twist-lock lacing, and the leather versions swap the textile upper for leather. Each product page states its own rating and markings.
The mid-cut Modulos are boots, so they are VAT-free when bought for your own use at work. See the rest of the Safety Jogger range, or our size and fit guide if you are between sizes.
