This winter work boot combines protective features with practical design, delivering solid performance across challenging environments.

The BOA rotary closure system ensures a quick, secure fit that adapts to your foot throughout the day, whilst the non-metallic toe cap provides protection without the weight.

Recommendations from our Unishore Expert

These winter work boots perform best when you need dependable protection in cold, wet, or hazardous environments. The BOA closure works brilliantly if you're moving between tasks throughout the day, as you can adjust the fit instantly without removing your gloves. The combination of water resistance and cold insulation makes them well-suited to outdoor work or warehousing in winter months. For maximum comfort during extended shifts, pair them with thermal work socks that complement the boot's insulation properties.

Step 1 : Stand upright on a hard surface with your heel against the wall and a blank sheet of paper taped to the floor

Step 2 : Have someone mark the longest part of the foot (Heel to toe) with a pen or pencil, repeat this for the same foot because sizes may differ per foot.

Step 3 : Use a ruler to measure the heel-to-toe length with the longest toe perpendicular to the wall
