4.0mm Kevlar midsole - 4.0mm Kevlar layer under the footbed for puncture protection, for ground carrying nails, banding, swarf and offcuts.

Rubber and plastic sole unit - A combined rubber and plastic sole. Rubber for the contact surface, a moulded plastic element to hold the unit's shape.

THE RANGE

Three tiers.

Pick the right one.

We don’t believe in over-spec’ing. If you mostly work indoors, save the £35. If you’re in groundworks year-round, the S3 is the floor — not the ceiling.

GUARANTEE

Quality of guarantee

6 MONTHS

Separately from the 28-day route above, we give a six-month quality guarantee on the goods we sell. It is set out in full at section 7 of our Terms and Conditions. In short: 

  • It runs for six months from the date of purchase, and covers manufacturing defects only. 
  • To claim, we need proof of purchase, a clear photograph showing the defect and the overall condition of the item, a description of the fault, and what the item has been used for. The photograph is what confirms the condition the item is in, so please send it with your first message. 
  • If we accept your claim we will replace the item or, where a replacement is not available, issue a refund or a credit. You will not be charged for the replacement or its delivery. 
  • It does not cover fair wear and tear, or damage caused by using the item outside its rated specification, EN ISO rating or working environment, for example exposure to chemicals or use in heavy manufacturing. The full list of exclusions is at section 7 of the Terms and Conditions. 

If a manufacturing defect appears more than 28 days after delivery but within six months, this is the route that applies. If you are not sure which applies, contact us using the details in section 7 and we will tell you.

UK 4-15 (EU 37-50) in both colourways. Khaki is the standard colour and LS-F055BK is the same boot in black, across the same size range.
It is lighter and it wipes clean, and it does not need waxing or feeding the way a cowhide boot does. It is not a leather boot substitute for everyone.
SBP SRA. We hold the EU type-examination certificate for this model, issued by DANAK under reference 001734 on 15 October 2025 and valid until 14 October 2030. SBP SRA covers the toecap and penetration resistance, with slip resistance tested on ceramic tile. It is not an S3 rating and we do not describe it as one.
