The Kasota 6-inch leather work boot with BOA® Fit System is built using direct attach construction which makes them more flexible, waterproof, and lightweight. The leather upper of the boot is fused to the sole of the boot without using any glue or stitching which also provides longer lasting waterproofing. The full grain leather wraps around the UltraDry™ waterproof membrane to keep you dry in wet conditions. We've reinforced the safety toe with a protective covering that is incredibly tough and abrasion resistant. The Memory Foam insole gives your feet immediate comfort. The comfortable sole is a long lasting, heat resistant material that keeps you safe and secure in any environment and provides excellent traction.
