Chainsaw boots sizing: avoid ordering the wrong fit

You order your usual number, pull on the new boots and find your heel moving inside a shell that feels a size too long. Then you read that someone else had to size up. Chainsaw boots sizing is not governed by one dependable size-up or size-down rule: UK comments differ by model and material, with a clear run-large pattern for the rubber Oregon Yukon but mixed advice for the leather Yukon. The notes below follow those UK review comments. We have not fitted the boots in a lab. A qualifying purchase through our links can earn us a commission at no extra cost to you.

In short

Treat sizing advice as specific to the exact boot. UK reviews repeatedly say the rubber Yukon runs large and often mention dropping one or two sizes plus adding an insole, while leather Yukon reviews disagree and Sarawak has too little fit evidence for a universal rule.

Why one chainsaw boots sizing rule fails

The tempting answer is to turn every review into a chart: usual size in one column, recommended size in the next. The evidence does not support that. It covers rubber and leather boots, several listing sizes and comments that vary greatly in detail. A line such as 'always go down two sizes' throws away the distinctions that help you avoid a return.

Start with the exact model and material. A review of the rubber Oregon Yukon is advice about that rubber boot, not automatically about the leather Yukon. The leather reviews do not show the same consistent direction. Sarawak adds another complication: a size appears in each title, and the UK fit commentary is sparse.

Then check whether a reviewer states both their usual size and the size ordered. 'Comes up big' is an alert, not a measurement. A comment that names EU 47 and EU 43 gives more context, although it still describes one wearer rather than a conversion for everyone.

Rubber Yukon runs large in UK reviews

The rubber Yukon produces the clearest pattern: many UK reviewers say it runs large. The exact corrections vary. Some report going down one size, some two, and there are more extreme examples. One wearer who normally takes a size 6 still found a size 5 loose. Another reported wearing EU 47 but ending up with EU 43 in this boot.

Those examples show why 'size down' is a warning, not a precise answer. The EU 47-to-43 report is a large adjustment, but one person's outcome should not become a universal Oregon Yukon size chart. The size 6 example shows that dropping a single size may not solve the problem for every foot.

Rubber Yukon reviewers also report that no insole is supplied and that they add their own. A boot tried straight from the box may feel more spacious than the same boot with the insole you plan to use. Look for whether the reviewer assessed the empty boot or fitted an insole first. One reviewer called a loose boot unsafe to wear. That is one review, not a fit standard, but if your foot still moves too much after the intended insole is in place, thicker socks are not the fix. For the material trade-off, see the rubber versus leather chainsaw boots guide.

Leather Yukon is not the same pattern

The leather Yukon reviews do not point consistently one way. Some reviewers say to size up, others say to size down, and comments also describe a wide fit. Do not carry the rubber Yukon's sizing rule across simply because the boots share the Yukon name.

A wide fit can be described imprecisely as 'too big'. Width and length are not the same problem. If your toes reach an acceptable point but the boot feels roomy around the foot, volume or an insole may be the issue. If the boot is plainly too long, changing only the volume underfoot does not correct the length.

Treat leather reviews as individual fit reports. Give greater weight to a comment that names the usual size, ordered size and any width issue, and ignore advice that silently combines rubber and leather. The top pick on the chainsaw boots comparison is a different listing: the SAFETOE Class 1 leather boot at about £108.88. UK reviews in that comparison say the fit was true to size, including a UK 9, and the title states memory foam insoles. Keep that note attached to the SAFETOE listing, not to either Yukon.

Sarawak sizes are in the listing title

Sarawak has a different evidence problem. The listings identify sizes, but there is very little UK commentary about fit. One title states UK 8 and EU 42. Other variants include UK 9.5 and UK 12. The three Sarawak ASINs are size variants of the same design, not three different designs.

The title matters when you follow a link or read a review. A fit comment on a UK 9.5 listing does not turn the UK 8 or UK 12 variant into a different boot, but it may not tell you how another labelled size will fit your foot. Confirm the size on the exact product page.

The only specific UK fit report says the Sarawak was half a size smaller than ordered. One report can flag a possible mismatch. It cannot establish that every Sarawak runs half a size small. There is no UK review evidence here for the UK 12 listing, so a confident statement about that size would be guesswork.

Insoles change fit, not the labelled size

An insole takes up internal volume and can change how firmly a boot holds your foot. That matters for the rubber Yukon, because reviewers say it arrives without one. If you intend to wear an insole, include it in the first proper fit check rather than deciding from the empty shell.

Separate two questions. Does the insole remove modest spare room and make the boot feel secure? Or is the boot so long that the insole is being used to rescue the wrong size? The reviews support an insole as part of the rubber Yukon set-up. They do not show that an insole can correct any amount of oversizing. Do not apply the missing-insole point to the leather Yukon or Sarawak unless those listings say the same thing.

Decide whether to keep or return the boots

When the boots arrive, check that the model, material and size on the listing match the order. If you bought a Sarawak variant, compare the UK or EU size in the title with what you ordered. A mismatch at this stage is not evidence that the whole model runs large or small.

Then reproduce the configuration in the relevant evidence. For the rubber Yukon, fit the insole you actually plan to use before a final judgement, and do not let it hide a length problem. Note whether the issue is length, width or general volume. Persistent looseness is a reason to exchange: one rubber Yukon reviewer regarded a loose pair as unsafe to wear. For leather Yukon, neither sizing up nor down is a guaranteed correction. For Sarawak, one half-size report is too little evidence to predict every variant.

If you reorder, record the first size, the sizing system, the material and the insole arrangement. Judge the replacement against that same boot, not against advice written for a different model.

What a single review can and cannot prove

A detailed review can show a problem worth checking. The rubber Yukon examples show that some buyers need a substantial reduction, and the Sarawak comment shows that a half-size mismatch has happened. They cannot prove a universal conversion. The EU 47-to-43 account remains one wearer's result. Size-up and size-down comments on the leather Yukon do not average out to 'true to size'.

Prefer reviews that name the exact model, material, normal size, ordered size and insole use. UK comments are the most useful for UK-labelled sizes. A non-UK report needs a clearly named sizing system before the number means anything. The rubber Yukon reviews can support a large-fit warning. They cannot support a rule for every chainsaw boot, or a promise that half a size will fix every Sarawak.
