Safety footwear certified to EN ISO 20345
The Striver is Caterpillar's core site boot, and it comes in more shapes than any other Cat style we carry: the classic lace-up boot in Black, Brown, Honey and Stone, a Striver Mid and a Striver Low shoe, a pull-on Striver dealer, and the newer Striver XL family with an internal waterproof membrane in 6 inch, 8 inch side-zip and dealer cuts. Every version pairs a 200 joule steel toecap with a steel penetration-resistant midsole and a water-resistant full grain leather upper; the standard Striver styles are rated S3 and the XL styles S7. The rating is stated on each product page.
Every Striver carries a 200 joule steel toecap and a steel anti-penetration midsole rated to 1,100 newtons, with an antistatic build and a fuel and oil resistant outsole.
The XL 6 inch, 8 inch side-zip and XL dealer add an internal waterproof membrane and a moulded TPU toe guard tested to the scuff cap (SC) standard, lifting them to S7 under EN ISO 20345:2022.
Pick the cut for the job: a lace-up boot for general site work, the Low or Mid for a smarter shoe or ankle boot, a dealer for slip-on convenience, or the 8 inch side zip for extra ankle cover.
The standard Striver runs from UK 4 up to UK 15 on some colours, one of the widest size spans on the site. The XL styles run UK 6 to 13. 9 Striver styles available.

The Striver is the boot most people picture when they think of a Cat work boot: a chunky injected PU sole, a padded collar and tongue, an energy-absorbing heel and a full grain leather upper that Caterpillar describes as water-resistant. The standard boot, the Mid and the Low all carry S3 under EN ISO 20345, which means a 200 joule toecap, a penetration-resistant midsole, an antistatic build, a water-resistant upper and a cleated outsole. The lace-up boot comes in Black, Brown, Honey and Stone, and the Mid and Low in Black, with a PU injected bump cap over the toe on the Mid and dealer to take the scuffs that wear out the leather first.
The Striver XL is the newer, heavier-duty branch of the family. It keeps the steel toecap and midsole but adds an internal waterproof membrane, a moulded TPU toe guard tested to the new scuff cap (SC) requirement and a TPU heel counter, which is what takes it from S3 to S7 under the 2022 standard. It comes as a 6 inch lace-up in several colourways, an 8 inch boot with a YKK side zip for quick on and off, and a pull-on XL dealer with twin elasticated gussets. Our safety standards guide explains how S7 relates to S3, and our waterproof safety boots collection groups every fully waterproof style we carry. The Striver sits alongside the Cat rigger boots and the rest of the Caterpillar range; for other pull-on styles see our dealer safety boots collection, for zip-entry boots our side-zip safety boots collection, and our size and fit guide covers how Cat sizing runs against other brands.
