The Caterpillar Second Shift combines full grain leather uppers and Goodyear welt construction to deliver exceptional durability against rough conditions, a quality Footwear Flix found essential for daily abuse. TheBootGuy measured the boots at 4.6 pounds in size 12, noting that while this weight is manageable for heavy-duty work, it feels clunky compared to lighter footwear options. Comfort is supported by a Climasphere breathable insole and padded collar after break-in, though TheBootGuy warned that the thick leather causes feet to become warm or swampy during hot weather. Additionally, the factory insole is glued down, preventing easy replacement with custom orthotics without modification. These boots fit workers prioritizing rugged protection and wide sizing availability over lightweight agility or high breathability.

Full grain leather and Goodyear welt construction
The Caterpillar Second Shift is built around a foundation of full grain leather uppers paired with Goodyear welt construction, a combination that reviewers consistently highlight as the primary driver of its durability. Footwear Flix describes this setup as being made to withstand rough conditions and daily abuse, noting that it is not merely a boot for looking good but one engineered to last through heavy use. TheBootGuy reinforces this assessment by calling the leather hard, thick, dependable, and strong, emphasizing that the solid piece of rubber outsole is glued directly to a welt rather than relying on layered materials that might peel away over time.
This construction approach results in a boot that feels exceptionally stable and robust underfoot. TheBootGuy notes that while it may not represent the absolute best welting process available for handmade boots, it delivers exactly what is promised at its price point: a heavy-duty work boot that lives up to claims of reliability. For workers who demand consistent performance from their footwear without needing premium pricing, this durable build quality provides a solid baseline that holds up against the physical demands of construction and industrial environments.
4.6 lb weight in size 12
TheBootGuy measured a pair of Caterpillar Second Shift boots in size 12 with laces and original insoles installed at exactly 4.6 pounds, establishing the baseline for its substantial feel on the foot. While this weight is not negligible compared to modern lightweight footwear options, TheBootGuy argues that it is manageable given the heavy leather construction and solid sole design. He suggests that while some more expensive boots might weigh significantly more, a basic non-waterproof, non-insulated work boot at 4.6 pounds allows workers to get away with wearing them as their primary daily driver without excessive fatigue.
Despite this measured weight being relatively reasonable for the category, Footwear Flix points out that these boots are undeniably heavy and can feel clunky initially if a wearer is accustomed to lighter shoes or boots. This discrepancy in perception highlights how the substantial build contributes to durability but demands an adjustment period for those prioritizing agility over ruggedness. The weight is a direct trade-off for the protective capabilities and long-term structural integrity that define the Second Shift.
TheBootGuy acknowledges that this boot should not necessarily be worn every single day without rotation, recommending that workers consider buying a second pair of the exact same model to allow one pair to dry out and relax while wearing the other. This advice stems from the understanding that at 4.6 pounds per pair, the boots are built like tanks with a lifespan that can extend nine months to a year under heavy use, making rotation a practical strategy for maximizing longevity.
Climasphere insole and padded collar comfort
Footwear Flix identifies the Climasphere breathable insole and padded collar as key components that deliver surprisingly good comfort for such a tough, rigid shell. The boot is not designed to feel like a sneaker out of the box, but it provides adequate support and security during long days on job sites or while walking city blocks once a short break-in period has passed. This combination of cushioning elements helps mitigate the stiffness inherent in full grain leather work boots, allowing for extended wear without immediate discomfort.
TheBootGuy adds that Caterpillar intentionally builds this boot slightly taller and wider inside to accommodate aftermarket insoles, recognizing that many workers will want to doctor up the fit with custom orthotics. However, he notes a significant limitation: the factory insole is glued down deep within the footbed, which prevents easy replacement without modification. While TheBootGuy gives them credit for this design choice at their price point, the glued-down nature of the Climasphere liner means that workers requiring specific medical support may need to invest additional effort to customize the fit.
Oil-resistant rubber outsole traction
The oil-resistant rubber outsole on the Caterpillar Second Shift provides solid grip on slick or uneven surfaces, a feature that Footwear Flix highlights as particularly useful for workers constantly moving through different environments throughout their day. This added safety component ensures stability in industrial settings where spills and varied terrain are common hazards. TheBootGuy describes the sole as heavy-duty and chunky but praises it as a good solid piece of rubber rather than fragile layered materials, reinforcing its reliability in demanding work conditions.
Thick leather causing warm feet
While the hard, thick full grain leather provides excellent durability and protection, it comes with a distinct ventilation penalty. TheBootGuy warns that because of this substantial leather combined with a standard polyester lining, the boots will get swampy by the end of the day in hot weather or during intense physical activity. He advises workers to open them up and dry them out after shifts to manage moisture buildup effectively.
Footwear Flix echoes this concern regarding breathability, noting that the tough construction can make the boot feel warm in hotter climates or during periods of high exertion. This limitation means the Second Shift is less ideal for outdoor work in extreme heat or for individuals who prioritize maximum airflow over rugged protection. The trade-off between heavy-duty weather resistance and temperature regulation is a defining characteristic of this model.
Steel toe versus composite options
TheBootGuy points out that the steel toe version of the Second Shift uses magnetic steel, which he describes as more practical for first-time buyers compared to composite toes. He argues that dropping something heavy on a composite toe could compromise its protective integrity in ways that might surprise new workers, whereas the steel toe offers reliable impact resistance from day one. This makes the steel toe variant a safer bet for those whose primary concern is maximum protection rather than metal detector compliance.
Sizes 5 to 16 medium and wide
One of the most inclusive sizing strategies in this price bracket belongs to Caterpillar, who make the Second Shift available from size five to sixteen in both medium and wide widths. TheBootGuy emphasizes that this coverage of the entire foot size spectrum is intentional, acknowledging that new entrants into the workforce often need decent boots but may have specific width or length requirements. This broad availability ensures that workers across all demographics can find a proper fit without compromising on the boot's core durability features.
Strengths

- +Climosphere breathable insole and padded collar deliver good comfort for a work boot after break-in.
- +Available in sizes 5 to 16 in medium and wide widths, covering the full spectrum of foot sizes.
Watch-outs
- −Heavyweight construction makes the boots feel clunky compared to lighter footwear options.
- −Thick leather and polyester lining can cause feet to become warm or 'swampy' during hot weather or intense activity.
- −Insole is glued down, which prevents easy replacement with custom orthotics without modification.
How it compares
At 4.6 pounds, this boot is significantly heavier than the Ever Boots Tank (~2 lb 4 oz) and Thorogood Infinity FD (2 lbs), making it feel clunky for those prioritizing agility over raw durability. Unlike the Wolverine DuraShocks SR Icon which uses a glued direct-attach construction that prevents resoling, the Caterpillar Second Shift features Goodyear welt construction for long-term repairability.
