Helly Hansen Chelsea Evolution Boa Wide Composite-Toe Safety Boots S3 - Black Grey - UK 8

While the boots offer waterproof protection, they are not specifically insulated for extreme cold. The BOA® system can become stiffer in very low temperatures. For prolonged exposure to freezing conditions, consider additional thermal socks.

No, machine washing is not recommended as it can damage the Helly Tech® membrane, adhesives, and other materials. Hand-clean them using a damp cloth and mild soap as per the care instructions.

'Metal Free' means the protective layer in the sole is made from non-metallic materials, such as composite or textile. This provides protection against sharp objects while allowing the wearer to pass through metal detectors without setting them off.

Microfibre is a durable synthetic material, but like all footwear, it can be susceptible to abrasion on very rough surfaces. The molded TPU toe bumper and heel overlay add significant protection to high-wear areas, enhancing overall durability.

The BOA® Fit System allows for one-handed adjustment, precise tension control, and a more uniform pressure distribution across the foot compared to traditional laces. It also offers quick release and is less prone to coming undone.

The 'Wide Fit' is designed with a broader last to accommodate individuals who find standard-width safety boots too narrow. It provides more volume and a more relaxed feel across the forefoot and midfoot.

The Helly Tech® membrane itself requires minimal direct maintenance beyond keeping the boots clean. Its performance is best preserved by ensuring the outer materials are clean and treated with appropriate waterproofing agents to prevent the fabric from becoming saturated.

Ensure the dial is fully pressed down before turning. If the issue persists, clean around the dial mechanism with a dry brush to remove any grit. Avoid using lubricants unless specifically approved for BOA systems, as they can attract dirt.

Check for significant wear or damage to the Helly Tech® membrane or seams. Ensure the tongue is properly positioned and the boot is securely fastened to prevent water entry. Moisture can also come from sweat; ensure the breathable lining is functioning by allowing boots to air out completely.

The BOA® system offers fine adjustments, but if the fundamental fit is incorrect (e.g., wrong size or width), it may not be adjustable enough. Ensure you have selected the correct UK size and width for your foot. The wide fit is designed for broader feet; consider if this is appropriate for your foot shape.

Use a damp cloth and mild soap solution. For persistent stains on microfibre, a dedicated cleaner for synthetic materials might be necessary. Always test cleaners in an inconspicuous area first.
