Use the CAT Footwear sizing information below to help select the best size. CAT provides U.S., UK, EU, and foot-length conversions for its footwear. Product-specific size and width availability may vary by boot or shoe style.
CAT Footwear Men's Boots
Use foot length as the primary sizing guide. Measure from the back of the heel to the end of the longest toe. CAT men's footwear is available in multiple widths on many work-boot styles.

Men's fit tip: Measure both feet and use the larger measurement. CAT work footwear is commonly available in Medium and Wide widths, but width availability varies by style.
CAT Footwear Women's Boots
CAT women's footwear uses its own U.S. sizing scale. Use foot length and the international conversions below to help select the best size.
| US Women's | 5 | 5.5 | 6 | 6.5 | 7 | 7.5 | 8 | 8.5 | 9 | 9.5 | 10 | 11 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|

| EU | 36 | 36.5 | 37 | 37.5 | 38 | 38.5 | 39 | 39.5 | 40 | 40.5 | 41 | 42 |
| Men's US Conversion | — | — | 4 | 4.5 | 5 | 5.5 | 6 | 6.5 | 7 | 7.5 | 8 | 9 |
Women's fit tip: CAT women's footwear is built on women's-specific sizing. Use the women's size offered on the individual product rather than relying only on a men's conversion.
CAT Footwear Width & Fit Guide
Many CAT work boots are available in both Medium and Wide widths. Width availability varies by product.
| Width | Fit Guidance |
|---|---|
| Medium | Standard CAT footwear width. Start here if you normally wear a standard-width work boot. |
| Wide | Provides additional room through the forefoot. Choose Wide if you normally purchase wide footwear or experience pressure across the sides of the foot in standard-width boots. |
Safety-toe fit: Steel, composite, alloy, and soft-toe CAT footwear can feel different through the toe box. Select the correct width rather than automatically increasing the shoe size.
Best practice: Try work boots with the type of socks you normally wear on the job and make sure your toes have room to move without excessive heel slip.
How to Measure Your Foot
1. Measure later in the day: Feet can expand slightly throughout the day, so afternoon or evening measurements generally provide the most useful fit reference.
2. Measure both feet: Stand with your weight evenly distributed and measure from the back of the heel to the end of the longest toe.
3. Use the larger foot: If one foot is slightly longer than the other, select your size based on the larger measurement.
4. Consider width: Length and width are separate fit considerations. If the length feels correct but the boot is tight across the forefoot, consider a Wide width when available.
