Overview

Portwest FE04 Girder Composite Mid Boot - Overview

The Portwest FE04 is a composite-toe mid boot built to EN ISO 20345:2022 S3S, rated for ESD-controlled environments. A BOA-style quick-release lace system replaces traditional laces for a secure, even fit, and the mid-height upper supports the ankle while staying easy to put on and take off.

Frequently asked questions

Is the FE04 suitable for ESD-controlled work areas?

Yes. It carries an ESD rating for handling static-sensitive components and working in anti-static-controlled environments.

What does the composite toe cap protect against?

It gives impact and compression protection to EN ISO 20345:2022 S3S, without the weight or cold-conductivity of a steel toe cap.

How does the BOA-style lacing work?

A dial on the tongue tightens or releases a steel wire lace, so you get an even fit without tying traditional laces.

Will these boots keep my feet dry?

The upper is water-resistant, so it handles damp ground and light rain. It is not a fully waterproof boot, so it is not rated for standing water.

Can I wear these through a metal detector?

Yes. The construction is non-magnetic and free of nickel and ferrous metal, so it will not trigger a metal detector on security-screened sites.

What sizes and colours are available?

Black/Green and Black/Grey, both in UK sizes 37 to 48.

Is the outsole resistant to fuel and oil spills?

Yes. The dual-density outsole carries FO fuel and oil resistance alongside SR slip resistance.
