How do I know which size to order?

Sizes shown are EU sizes with the equivalent UK size beneath each button. If you sit between two sizes, most safety boots run true to size, but if you intend to wear thicker work socks (or orthotic insoles) sizing up by half a size is sensible. See our full size guide for brand-specific notes.

How long does delivery take?

Despatch times differ by line. Items held in our own stock and ordered before 1pm on a working day are despatched the same working day. Selected brands including Portwest and Base Protection are despatched the next working day when ordered by 4pm. Most other orders are despatched within 3 to 5 working days of confirmation, and extended-range lines show a longer lead time on their own page. Courier transit after despatch is typically one to two working days. We do not offer a guaranteed next-day delivery service, and all timescales are estimates. Delivery is free on orders over £75; orders under that threshold carry a £5.95 shipping charge.

Can I return them if they do not fit?

Yes. Unworn boots in their original packaging can be returned within 30 days for a full refund. Try them on indoors, on carpet, before going outside. Once a boot has been worn outside the sole shows wear and we cannot accept the return.

This sock has wool content which is a great conductor of heat and will keep your feet warm in colder climates. There is cushioning throughout the inside of the sock which will help to keep the heat in and reduce friction. The mesh ventilation at the inner ankle will allow your foot to breathe and the ribbed knit will help prevent any irritation from contact with the shoe when walking.
